HTML, CSS and JavaScript on the web

HTML, CSS and JavaScript - an overview

HTML, CSS and JavaScript - each of these technologies has its own purpose, purpose and function. The use of these three programming languages allows for a rich user interface and a wide variety of interesting features. Let's consider the features of these technologies and what they mean.

Html

Internet users often ask questions in the search bar: "How to develop a website in HTML?". Despite this, HTML is not a complete programming language. The main functions of HTML are to set the location of page elements, indicate their types and place links to link the portal pages. It stands for Hypertext Markup Language, its literal translation is "Hypertext Markup Language".

To make it easier for you to understand this technology, imagine a house. Looking at the building, we see its exterior. The tags on the page are the little bricks that were used to build the house. All bricks must be neatly laid out, otherwise the building will look unpresentable or completely unsuitable for living. Also on pages, it is important to correctly compose the structure of the page and correctly place HTML tags.

The first version of HTML was created in 1991. With the development of the Internet, the language itself grew up. Its capabilities are constantly expanding (new tags are being introduced).

The last major version was released in 2014. HTML5 introduces many new features to the language, including support for embedding audio and video. Of the advantages of this technology, it is worth noting that it is completely free and can be easily integrated with basic languages. HTML has clean and consistent markup.

CSS

Tag elements do not look presentable without good graphic design. To solve this problem, the CSS language was developed.

CSS is a cascading style sheet. It stands for Cascading Style Sheets. After creating the structure and filling the document, it is necessary to make it outwardly with high quality. CSS allows you to change the style, size of elements, make them attractive.

Let's go back to our house example. After building a house, you need to give it a beautiful look, that is, paint it in the right colors. This is the graphic design.

We sorted out the style. Now it remains to animate it all with JavaScript.

JavaScript

JavaScript is one of the popular programming languages ​​and is abbreviated as "JS". Today it is used by almost every web resource for powerful and complex functions. Note that this is a more complex language than HTML or CSS. It was designed to "animate" web services, mobile, web applications and sites, that is, so that interface elements react in a certain way to user actions. It is JS that allows you to develop interactive sites with dynamic elements.

Let's go back to the house example. JS is the elevator that takes people to the desired floor. Entering the elevator, the user clicks on the desired floor button and then he gets to a specific floor. The same is on the site. The user just needs to click on the button, and the JS will perform the action. These can be pop-ups on the screen, verification forms, animations, various special effects, call to action (CTA).

There is actually a lot more technology in web development. We've covered the main ones. Now you understand that it is simply impossible to develop a good website using HTML alone. If you do not know the basics of programming, you can order a full-fledged website with a modern design from experienced specialists. Developing a good website always requires investment.
