Unveiling the Aesthetics: A Comprehensive CSS Introduction for Web Styling Mastery
Cascading Style Sheets, commonly abbreviated as CSS, functions as a specialized style sheet language, exclusively designed to format HTML elements and dictate their presentation on various mediums such as screen, paper, and other forms of media. CSS can be used to style text, fonts, colors, margins, padding, borders, and much more.
How CSS Works
CSS works by applying styles to HTML elements. Styles are defined in CSS rules, which consist of a selector and a declaration block. The selector specifies the HTML element to which the style should be applied, and the declaration block specifies the properties of the style.
For example, the following CSS rule applies the color red to all <p> elements:
p {
color: red;
}
Types of CSS
There are three main types of CSS:
- Inline CSS: Inline CSS is applied directly to an HTML element using the
styleattribute. For example, the following code applies the colorredto the first<p>element:
<p style="color: red;">This is a red paragraph.</p>
- Internal CSS: Internal CSS is defined within the
<head>section of an HTML document. Internal CSS is applied to all elements in the document. For example, the following code applies the colorredto all<p>elements:
<head>
<style>
p {
color: red;
}
</style>
</head>
<body>
<p>This is a red paragraph.</p>
<p>This is another red paragraph.</p>
</body>
- External CSS: External CSS is defined in a separate .css file, which is linked to the HTML document using the
<link>tag. External CSS is applied to all elements in the document. For example, the following code links thestyle.cssfile to the HTML document:
<head> <link rel="stylesheet" href="style.css"> </head> <body> <p>This is a red paragraph.</p> <p>This is another red paragraph.</p> </body>
