What is CSS?
A website is built using code, such as HTML, Javascript, PHP and CSS. To simplify, we can say that the HTML code tells the browser what content should appear on the website, while the CSS code defines how everything should look. CSS stands for “Cascading Style Sheets”, and is a separate file stored together with the other files on the server. The file can, for example, be named “style.css”, and is linked to from the HTML code so that the browser can locate it.
How does the CSS code work?
The styling is set up by defining colors, sizes, and other variables for the different elements in the HTML code. For example, the main heading is defined with <h1>CSS?</h1> in the HTML code. In the CSS file, it might look like this when you define the appearance of the main heading: h1 { font-size: 40px; font-weight: bold; font-color: red; } We have then told the browser that the main heading should have a size of 40px, use bold text, and be colored red. You also use different “class” and “id” names to give different appearances to various elements of the same type. For example, you can assign different font sizes and colors to two subheadings (h2 tag) by giving them different names in both the HTML and CSS code. Without the CSS file, this page would have looked like this:
