What is CSS
CSS stands for Cascading Style Sheets. It is a style sheet(CSS) language. It is used to describe the look and formatting of a document(file) written in a markup language. It provides an additional feature to HTML. It is also used with HTML to change the style of web pages and user interfaces. It can also be used with any kind of XML documents(file) including plain XML, SVG, and XUL.
CSS is used along with HTML and JavaScript in most websites to create user interfaces for web applications and user interfaces for more mobile applications.
What does CSS do:
- Add new looks to your old HTML documents.
- Completely change the look of the website with only a few changes in CSS code.
Advantages of Using CSS:
- CSS Save Lots of Time: A CSS style is saved in external CSS files so it is possible to change the whole website by changing just one file.
- Easy Maintenance: CSS provides an easy means to update the formatting of the documents and to maintain consistency across multiple documents(files). Because the text of the entire set of web pages can be easily controlled using one or more style sheets.
- Pages Load Faster: CSS enables multiple pages to share the formatting information, which decreases the complexity and repetition in the structural contents of the documents(file). It decreases the file transfer size, which results in a faster page loading.
- Provide more attributes: CSS provides more detailed attributes than plain HTML to specifies the look and feel of the website.
