CSS

CSS (Cascading Style Sheets) is a stylesheet language that is used to describe the appearance and formatting of a document written in HTML (Hypertext Markup Language). It allows developers to separate the content of a website from its presentation, making it easier to maintain and update the look and feel of a website over time.

CSS consists of a series of rules that specify how elements on a webpage should be displayed. Each rule consists of a selector, which identifies the element or elements that the rule applies to, and a declaration, which specifies the styles that should be applied to the selected element or elements. The declaration is made up of one or more properties, each of which has a value that specifies the desired style for the property.

For example, the following CSS rule specifies that all paragraphs on a webpage should be displayed with a font size of 18 pixels:

Copy code
p {
font-size: 18px;
}
CSS can be applied to a webpage in a number of ways, including directly in the HTML document using the “style” attribute, or in an external stylesheet that is linked to the HTML document using the “link” element. It is also possible to use JavaScript to manipulate the styles of a webpage in real-time.

In conclusion, CSS is a stylesheet language that is used to describe the appearance and formatting of a document written in HTML.
