CSS (Cascading Style Sheets) is a stylesheet language used to describe the presentation of a document written in HTML or XML. It allows you to style and layout web pages, alter the font, color, size, and spacing of your content, split it into multiple columns, or add animations and other decorative features.
Here are some key points about CSS:
- CSS is designed to enable the separation of content and presentation, including layout, colors, and fonts.
- It improves content accessibility, provides more flexibility and control in the specification of presentation characteristics, and enables multiple web pages to share formatting by specifying the relevant CSS in a separate .css file.
- CSS can be used for basic document text styling, creating layouts, and adding effects such as animation.
- The syntax of CSS is relatively simple, and it can save a lot of work by controlling the layout of multiple web pages at once.
- External stylesheets are stored in CSS files, which can be linked to multiple HTML pages, making it easier to maintain and update the styles.
