When you decide to start learning a programming language like HTML or CSS, it is important to focus on a comprehensive approach. Whether you are just starting and learning the basics or you already have some knowledge and want to explore more advanced levels of it, it is always good to know the first and most important thing about it.
In this case, the most important thing is to find out what CSS actually does. Also, a good thing to know is that HTML and CSS are always working together. One takes care of the webpage structure and the other makes it look good while adding levels of interaction.
If you are looking to become a web designer, it would be the best for you to know both languages. Whether you do the coding or not, it would be better if you fully understand how they work.
Cascading Style Sheets
CSS stands for documents which are applicable to HTML because they contain styling rules for HTML. CSS determines which style rule should be executed while running multiple styles rules. The term cascading describes how the filtering of general rules works. Out of all general rules, the specific one is encountered and chosen to do its work. Basically, that is how it works.
CSS has a simple task of mashing styling rules in among HTML with one goal, to keep the documents neater. Web browsers have the ability to read CSS. The marked document is taken by the browsers and they apply the styling rules to the elements within the document. With the developing of the web browsers, comes the development of their support of newer styling proposals. These things always evolve together.
The basic thing that everyone who is into this area needs to understand is how CSS syntax works. It comprises a few fundamental pieces like values, properties, declarations, selectors, and rules. When they all work together, it is what gives your HTML pages their beautiful appearance.
So, now that you have the basic understanding of what CSS actually is, the best thing to do would be attending a course that will fill you in on how the pieces are put together and how you can manipulate them in order to create something new. It can become a bit confusing without the proper knowledge. That is why the course would be recommended.
