Since each of these three languages serves a different purpose, web developers generally use separate files for each one. This idea is called “separation of concerns” — each file should have a different function within the site as a whole. This article looks at mobile-specific performance considerations. You know web performance is important, but which of the following is well versed in html5, javascript, and css? what constitutes web performance? Another option is user groups — using a group of people outside your development team to test your site. This could be a group of friends or family, a group of other employees, a class at a local university, or a professional user testing setup, where people are paid to test out your site and provide results.

Some real estate developers decide to buy up a lot with a house on it, demolish the house, and put in some fancy apartments. Although you could technically include all the code in one HTML file, that will eventually lead to repetitive code as you grow your site. You can eat, sleep, make meals… anything that you do at home, really! This corresponds to the three different types of files that you can use in your first website. Let’s imagine that you are in charge of planning the layout of a new neighborhood in the city.

Different types of client-side validation

You can access any elements through the Document Object Model API (DOM) and make them change however you want them to. If you remember our example HTML page, we had elements which were pretty self-explanatory. For example, I stated that I would change the color of the level one heading h1 to red. With CSS you can set the colour and background of your elements, as well as the typeface, margins, spacing, padding and so much more.

CSS is a style sheet language used to specify the way different parts of a webpage appear to users. In other words, it’s a way to add some style and additional formatting to what you’ve already built with HTML. Unlike web designers, front end developers aren’t concerned solely with how a website looks.

HTML Style Guide

The Learning and getting help article provides you with a series of tips for looking up information and helping yourself. If you are still stuck, feel free to post a question on our Discourse forums. We have tried to make learning front-end web development as comfortable as possible, but you will probably still get stuck because you don’t understand something, or some code is just not working. First, you’ll use HTML to create the basic structure of your website. This includes deciding what your main pages will be as well as how they’re laid out. HTML will help you build a main page consisting of a header and some body text, as well as an image at the end.

That agreement is called the Application Programming Interface or in short, the API. As such, web designers must know HTML, CSS and JavaScript to bring their designs to life. This is true even if they work with pre-templated design programs like WordPress, Wix or Squarespace. While these tools can help a designer implement most of their vision, there’s nothing quite as handy as being able to customize your page design yourself.

Basic CSS resets to apply in every app

The iteration is taken care of internally instead, making it more performant too. What’s less straightforward is attaching multiple styles to any one node. Thanks to the DOM, we can use methods like getElementById() to access elements from our web page.
