CSS Introduction
CSS, or Cascading Style Sheets, is a styling language used to describe the look and formatting of a document written in HTML. CSS allows you to separate the presentation of a website from its structure, making it easier to maintain and change the look of the site.
CSS is a stylesheet language that is used to control the presentation of an HTML document. CSS is the acronym for Cascading Style Sheets and it’s the technology used to style web pages.
Here's a simple example to illustrate the use of CSS:
<html>
<head>
<style>
h1 {
color: blue;
text-align: center;
}
p {
font-size: 20px;
text-align: justify;
}
</style>
</head>
<body>
<h1>This is a heading</h1>
<p>This is a paragraph. This is a paragraph. This is a paragraph. This is a paragraph.</p>
</body>
</html>
In this example, we have defined two CSS rules. The first rule is for h1 elements, and sets the text color to blue and aligns the text to the center. The second rule is for p elements, and sets the font size to 20 pixels and aligns the text to the justified.
When this HTML code is rendered in a browser, it will display a blue heading that is centered on the page, and a paragraph of text that has a font size of 20 pixels and is justified.
CSS allows you to create a consistent look for your website, and make it easier to change the look of the site in the future. You can define styles for individual elements, such as headings and paragraphs, or you can define styles for classes of elements, such as all blockquote elements or all elements with a specific class.
In conclusion, CSS is a crucial component of web development and is used to control the presentation and styling of HTML documents. By using CSS, you can create a consistent and attractive look for your website, and make it easier to update and maintain the look of the site in the future.
