Style Rules in CSS
CSS comprises of style rules interpreted by the browser and then applied to the corresponding elements in your document. A style rule is made of three parts −
- Selector - A selector is an HTML tag at which a style will be applied. This could be any tag like <h1> or <table> etc.
- Property - A property is a type of attribute of HTML tag. Put simply, all the HTML attributes are converted into CSS properties. They could be color, border etc.
- Value - Values assigned to properties. For example, the color property can have value either red or #F1F1F1 etc
Syntax
You can put CSS Style Rule Syntax as follows:
selector {
property: value;
}
Example
Here's a complete example showing how CSS style rules work:
<!DOCTYPE html>
<html>
<head>
<style>
h1 {
color: blue;
font-size: 24px;
}
p {
color: green;
margin: 10px;
}
.highlight {
background-color: yellow;
padding: 5px;
}
</style>
</head>
<body>
<h1>Welcome to CSS</h1>
<p>This is a normal paragraph.</p>
<p class="highlight">This paragraph has a yellow background.</p>
</body>
</html>
Types of Selectors
CSS supports different types of selectors:
-
Element Selector - Targets HTML elements (e.g.,
h1,p) -
Class Selector - Targets elements with specific class (e.g.,
.highlight) -
ID Selector - Targets element with specific ID (e.g.,
#header)
Multiple Properties
A single selector can have multiple property-value pairs:
h2 {
color: red;
font-size: 18px;
text-align: center;
margin-bottom: 20px;
}
Conclusion
CSS style rules follow a simple selector-property-value structure. Understanding this fundamental syntax is essential for styling web pages effectively.
