What is CSS?

CSS is a programming language used to define the style and appearance of a document that has been written using a tag language, What HTML. Also known as cascading style sheets, is the one used to give colors, indicate fonts or even highlight aspects such as the space between items to give style to a website.

It is one of the fundamental pillars of development and web design, as well as one of the biggest nightmares of any programmer. Since it is the set of rules that are indicated to browsers to display the items on a page, performing the wrong instructions can lead to the presentation of a website that is impossible to view correctly.

Generally, each of the CSS rules used is made up of a series of properties, or properties, which have values that indicate the presentation of all the content dictated in HTML; and, apart from this, selectors that indicate which items will be affected by these properties and their values.

This whole set is what makes up the files that have to be indicated to the browsers to establish the appearance of the web pages. In spite of everything, the complexity of its handling and the need to learn programming notions are something that usually leads many to rely on predetermined templates or other much more comfortable solutions that make these tasks infinitely simpler, even when giving up the total personalization.

What is CSS for

CSS is used to style any website and do it with the desired rules. It is the language with which the programmer and the browser communicate to indicate to the latter how to distribute the contents of a website based on the instructions indicated in the corresponding files.

In turn, its main purpose is to obtain different styles tailored to the needs of each page. Even though, unfortunately, it requires extensive programming knowledge and great notions of HTML in addition to obtaining the perfect connection between style and content.
