Tags like ;font; were introduced in HTML version 3.2 and caused a lot of problems for developers. Because websites had different fonts , colors, and styles, it was a long, painful, and expensive process to rewrite the code. Thus, CSS was created by the W3C to solve this problem. The relationship between HTML and CSS is very strong. As HTML is a markup language (the foundation of a website) and CSS is focused on style (the entire aesthetic of a website), they go together. CSS isn’t technically a necessity, but you probably wouldn’t want to look at a site that only uses HTML as that would look completely abandoned.

Advantages of CSS

The difference between a website that implements CSS and one that doesn’t is huge and remarkable. You may have seen a website that doesn’t load completely or has a white background with blue and black text. This means that the CSS part of the site was not loaded correctly or does not exist. And this is what an HTML-only website looks like. I think you’ll agree with me that this isn’t very pretty, right? Before using CSS, all styling had to be included in the HTML markup. This means that you should separately describe the entire background, font colors, alignments, etc. But CSS allows you to style everything in a different file, thus creating the style separately. And later, integrate the CSS file on top of the HTML markup. This keeps the HTML markup clean and easy to maintain. In short, with CSS you no longer need to repeatedly write what individual elements look like. This saves time, shortens the code and reduces the chance of errors. CSS allows you to have multiple styles on an HTML page, making the customization possibilities almost endless. Nowadays, this is becoming more of a necessity than a simple feature.

How CSS Works

CSS is a very powerful tool that makes it possible to create different functionalities instead of using JavaScript or another heavier language. If used in moderation, CSS can provide a great experience for developers and users of web pages. With Cascading Style Sheets it is possible to create complex animations, create effects using parallax , which makes it appear that the background image has a different depth from the others, create interactive websites and also games with HTML5 and CSS3. CSS uses a simple English-based syntax with a set of rules that govern it. As we mentioned earlier, HTML was never intended to use styling elements, just page markup. It was created to describe the content only. For example: ;p;This is a paragraph.;/p;. But how do you style the paragraph? The CSS syntax structure is very simple. It has a selector and a declaration block. You select an element and then declare what you want to do with it. Pretty simple, right? But there are some rules you need to know. This is also simple, don’t worry. The selector points to the HTML element you want to style. The declaration block contains one or more declarations separated by semicolons. Each declaration includes a CSS property name and value, separated by a colon. A CSS declaration always ends with a semicolon and declaration blocks are surrounded by curly braces.

List of basic CSS commands

There are so many options between selectors, properties and values that it can be very difficult for a developer to remember them all just relying on memory. That’s why we decided to create a List of Basic CSS Commands (CSS3 Included) that will serve as a help for you who are learning about what CSS is. This document has been strategically structured and divided into sections to facilitate reading. Download the List of CSS Commands in PDF by clicking here and deepen your knowledge of what CSS is.

How to Create a Stylesheet

Creating a style sheet is very simple. Just open your code editor, like Sublime, and create a new document. Once created, save it as Estilo.css, even without having written anything yet (this .css is what defines a file to be recognized by the browser as a style sheet).

Evolution of HTML

HTML was developed by Tim Berners-Lee at CERN (European Organization for Nuclear Research), with the help of the NeXTSTEP development environment, and was initially a collection of tools to handle research and communication between its creator and other people.

With the evolution of the internet, the solution gained worldwide attention. The first versions were flexible, and this helped beginners in the field. Over time, the structure became more rigid, but even today browsers can interpret web pages created the old way through backward compatibility.

Formally, the specifications were only defined in the 1990s. Then the evolution of HTML began , with an HTML working group being created which, in 1995, published the HTML 2.0 version. At the end of 1997, HTML 3.5 was released and, with it, the W3C working group began to focus on the development of XHTML. They continued with the release of HTML 4.01 versions in 1999, of XHTML in 2000, and finally we arrived in 2014, when HTML5 was launched, which is still used today, as well as its updates.

We saw that several versions of HTML were released until we reached the one we use today, but what is the difference between HTML and HTML5 ?

Difference between HTML and HTML5

In older versions, content structuring was done mainly by generic elements, such as ;div;and ;span;. In HTML5 we have semantic tags that refer to the purpose of the element, such ;header;as the header, ;footer;the footer, ;section;to separate sections, among others.

Furthermore, today, with HTML5 we have native support for audio and video , allowing us to embed them directly on the page. Forms can also cover more types of fields in the new version: we now have email, number, date and specification fields available that generate native validations on the elements.

However, it is important to know that HTML5 is not a static version. It is still being developed and improved today, with features and features being added from time to time.

HTML vs XML: what are the differences?

Both XML (Extensible Markup Language) and HTML are markup languages used on the web, but despite this, they have different purposes and structure.

XML is designed to represent information in a hierarchical and readable way, both for humans and machines, not being concerned with visual presentation or having a pre-defined structure, but with describing the data structure in a consistent and portable way. In Brazil, it is the most used format for issuing invoices.

HTML is specific to the creation and presentation of content on web pages, being more restricted as it has pre-defined elements and structure, focusing on visual presentation and how the elements should be displayed in the browser. It is commonly used in website building.

We can consider that the main differences are: while XML is used to store and transport data, HTML is used to create web pages with formatted content that allows interaction.

How does HTML work?

As previously stated, HTML is used to structure and format the content of web pages through tags, which will be interpreted by the browser. To make this interpretation possible, it is important to declare which version of HTML will be used .

This declaration is made through ;!DOCTYPE html;, ensuring that the browser correctly interprets the code. It is important to note that this is not an HTML tag, but rather an instruction for the browser that must be placed at the beginning of the document without spaces between it.

These supplier companies develop the game software and then place it on the different servers of online casino platforms. They are continuously providing maintenance service to resolve issues or glitches related to the operability of the games. The online casino market is highly competitive, the Betway company is concerned with keeping up to date with the most original, new and fun titles, without forgetting classic casino games such as roulette, slots, poker and Blackjack. It is essential to request the services of companies with verifiable experience and recognition on the web in order to count on the work of trained personnel in the field, above all committed to providing the best titles and improving users’ gaming experience within a safe, exciting and fun environment. and with the greatest possible realism.

The programming must be articulated taking into account the most popular payment methods among users. Dedicating yourself to web and video game development involves a large investment of time at the computer, as well as constant specialization and additional training to stay up to date with technological developments in online casino games.

Programming, axis of web development

The development of different online casino and betting sites requires programming, logically, they are technologies oriented towards products and services that require software for their operation. Defining programming in general is a bit complex, but it can be said that it is based on creating precise instructions for devices to carry out a specific task, whether simple or complex. As a result, the software is expected to be able to fulfill all the functions corresponding to online casinos, such as: joining the game and consolidating a Bet, showing the results of a game and processing deposits and withdrawals electronically.

Programming requires prior study to learn the languages specific to this race. Developers who are just starting out should research suitable languages for developing virtual games. The Java language is generally used to develop casino games because it is compatible with a variety of devices and operating systems. People who want to develop games for the web with accessibility and the possibility of playing in an online casino from their computer or mobile phone should know the HTML5 language, widely used for the structure of web pages.

The most frequent programs in the online casino theme are CSS3, Javascript and SQL, they fulfill different functions and each of them has its own characteristics, with respect to the games available on the screen for players. Casino administrators are responsible for managing the server, which must be powerful enough to support the connection of different player clients at the same time.

In the case of a large user traffic, it is preferable to choose languages that allow a good volume of connections, such as Erlang, C+++ or Java. It’s not always about programming, casino game development companies are also responsible for designing the games and integrating other necessary elements such as the probabilities of winning or losing, volatility, graphic aesthetics, sound effects, among others…

Random Number Generators

Designed to generate random data without configuring a distinguishable sequential pattern, this technology is commonly implemented through programming codes in a hardware device. A Random Number Generator’s main objective is to avoid repeating results and optimize the players’ experience.

In online casinos, RNG works to guarantee unpredictability and fairer outcomes for the user, such as card shuffling, for example. In the gaming world, it is a solution to determine item drops in RPG games, so that rarer elements have a lower drop rate, making the experience more interesting.

Animation and graphics technology

As the years go by and technology advances, games are increasingly improved, with graphics and animations that border on reality. This is all possible thanks to highly complex resources that enable the creation of interactive and visually very attractive titles. Among these solutions, three of them stand out in the current market: HTML5, Cascading Style Sheets and JavaScript. We can recommend a new online casino, which is reliable and popular among Portuguese players – leoncasino.

The first of them is nothing more than a programming language used to develop online and casino games for multiple platforms. In turn, CSS is an aspect of graphic design that uses HTML codes to create animated pages on a website. The latter makes it possible to build interactive functions in HTML documents, as well as bringing more flexibility to creators when integrating web resources.

Web Server Technology

In order to provide dynamic content in a safe and bug-free way, websites and online gaming platforms need web servers to host their material on the network. Currently, five of them are among the best known and used by these companies: Apache, Nginx, Microsoft Internet Information Services, Node.js and Jetty.

Compatible with Windows, Linux, masOS and other systems, Apache is one of the most popular among them. Nginx is known for its good performance and efficiency for highly scalable games. As it could be otherwise, Microsoft IIS is commonly used forcompatible titles on Windows, while Node.js is based on Google Chrome’s V8 engine. Jetty is an open source server used for games on the Java platform.

Online payment systems

With increasing possibilities for monetization through games, it became necessary to develop new technologies to guarantee the security of users’ data and transactions on the network. It is therefore possible to deposit and withdraw amounts through credit cards, electronic wallets, bank transfers andcryptocurrencies, all ensured by software that guarantees the integrity of players and their money.

Unlike the relatively established segments of HTML and CSS, JavaScript is being actively developed through the efforts of application platform developers and the utility programs that run Web applications. This chapter examines several ways that Web developers are using JavaScript and provides an overview of the Angular and React client libraries.

HTML

HTML is a standard markup language used to create Web pages and Web applications. Its elements define standard page blocks and also represent formatted text, images, data entry forms, and other structures. When a browser makes a URL request to retrieve a page or application, an HTML document is returned first. This HTML document may contain a link or additional information about the design or layout in the form of CSS, and behavior in the form of JavaScript.

CSS

Cascading Style Sheets (CSS) define the design and layout of HTML elements. CSS styles can be applied directly to an HTML element, defined separately on the same page, or defined in a separate file referenced on the page. A cascade of styles is defined based on how they are used to select a particular HTML element. For example, a style can be applied to the entire document and overridden by the style of an individual element as needed. In the same way, the style of an element can be overridden by the style applied to the element’s CSS class, which in turn can be overridden by the style applied to a particular instance of the element by its identifier.

CSS preprocessors

CSS stylesheets do not support conditional logic, variables, and other programming language features. Thus, large stylesheets often contain repetition because the same colors, fonts, and other parameters can be applied to different HTML elements and cascading stylesheet classes. The use of preprocessors for CSS stylesheets enforces the “Don’t Repeat” principle by adding support for variables and logic.

The most popular CSS preprocessors are Sass and LESS. Both of these extend the capabilities of CSS stylesheets and provide backward compatibility with them. This means that a regular CSS file can be opened to work in Sass or LESS. Sass and LESS are developed in Ruby and JavaScript, respectively, and are typically used as part of a local development process. Both of these solutions offer command line facilities and built-in support for execution in Visual Studio using Gulp or Grunt tasks.

JavaScript

JavaScript is a dynamically interpreted programming language that was standardized in the ECMAScript specification. It is a programming language for the web. Like CSS, JavaScript can be defined as attributes in HTML elements, as script blocks on a page, and in individual files. As with CSS, it is recommended that JavaScript code be stored in separate files to maximize its separation from HTML code, which is contained in individual web pages or application views.

When working with JavaScript in a web application, you typically need to perform a number of tasks:

• Selecting an HTML element and retrieving or updating its value;
• Requesting data from the webAPI;
• Sending a command to the webAPI (and responding to a callback function with its results);
• Performing validation.

These tasks can be done with JavaScript alone, but you can also use many off-the-shelf libraries to make this much easier. One of the first and most popular libraries is jQuery, which is still widely used to simplify these tasks when working with web pages. The jQuery library contains few features for single-page applications, so it’s better to use Angular and React in such scenarios.

One of the main advantages of CSS is the ability to create a uniform design for all pages of a website. This is achieved by creating a set of style rules that can be applied to any page on the site. Thus, a change in one place can affect all pages. CSS can be used to solve the simplest and most complex tasks at the same time. The language supports many features such as animations, transformations, transitions, and other effects that can be used to create interactive user interfaces.

There are several ways to use CSS on web pages, including internal, external, and inline. Inline CSS involves inserting style rules directly inside HTML tags, while external CSS involves creating a separate CSS file that is then connected to the HTML page. Inline usage combines the two methods.

CSS has a number of advantages that make developers love this language.

• Separation of content and design. Thanks to the use of CSS, you can change the appearance of the page without having to correct its content;
• Versatility. CSS is used for styling web pages on all devices and platforms. The language provides a uniform style and layout of the page regardless of the browser or device used for viewing;
• Flexibility and control. With CSS, you can create multi-level and complex page design structures and easily manage and modify them. This gives developers more freedom to create customized design solutions;
• Improved performance. Using CSS can improve website performance because CSS files are cached on the visitor’s side of the website. This means that the browser can load them only once and reuse them for other pages on the site.

Master HTML

We recommend that you first familiarize yourself with the history of HTML versions to better understand the logic of the evolution of the hypertext markup language. After that, proceed directly to the practical training:

• HTML tags;
• HTML attributes;
• HTML events.

If for some reason you are not ready to install a code editor and work with it, you can use an online editor directly in your browser.

Learning CSS

After learning the basic HTML tags, you need to move on to learning CSS properties and selectors. And we also recommend that you put your new knowledge into practice in the code editor to see how it works right away.

After getting a little familiar with basic tags, properties, and selectors, we recommend moving on to more complex tasks. Now you’ll definitely need a standalone code editor – Sublime Text, Atom, Visual Studio Code, or another.

There are many options for practice:

• Find a website with a simple design on the web and try to recreate it using HTML and CSS;
• Find PSD mockups and make the same layout;
• Search for a video on YouTube with the process of page layout and follow the author’s steps;
• Try online HTML and CSS tutorials. There are quite a few of them on the web, but most of them are paid;
• Practice as much as possible! Feel free to look for information and tips on the Internet. In the beginning, you can’t do without it. Over time, you will become more independent and less likely to “Google” the tags or properties you need.

Online learning

A few words about online learning. Nowadays, there is a huge amount of information freely available on the Web. But there are a few things to consider:

• How relevant is this information?
• Is it sufficiently structured and well presented?
• How exactly can you use the knowledge and skills you’ve gained?
• The course “Frontend development. Junior coder”
• Frontend development. Junior coder
