The full name of CSS is Cascading Style Sheet, which means cascading style sheet. CSS is used to improve the rendering of HTML markup content. Using CSS we can define different ways of displaying content based on media.

The following is a summary of the advantages of CSS:

1. CSS requires less code

We can define values ​​with values ​​in the public style class attributes, and can use the same class in different locations, so we can use less code to achieve more functions. Less code means less bandwidth consumption and ease of maintaining content.

2. Easy to maintain

When we define styles globally or in a common place, any changes become easy to operate. For example, in the website we display all the names of the products using specific style attributes. Now we can change the style throughout the site by changing the style class for the product name in an external stylesheet. We can keep multiple stylesheets and use them as needed. Using the property inheritance approach, you can easily maintain different styles of the same markup.

3. Content with a higher code (tag) ratio

We can achieve higher code ratio content in the page by using CSS, because we can change the style The declaration is converted to an external file. This is important from a search engine perspective. We can provide fewer tags (style tags) and more content to the spider for indexing.

4. Download page

When the browser caches the style sheet page, the page loads very quickly. Every time I use the same CSS for a different page of the same site, the style classes are not loaded from the server.

5. Flexibility in defining styles

Name cascading means that we can use multiple styles and give priority to local styles. We can override the declared global style and assign the style locally to the markup.
