Selectors in CSS

Selectors in CSS are tools used to apply styles to specific elements in HTML documents. They enable developers to target elements based on their type, class, ID, attributes or relationship to other elements. CSS selectors are essential for creating visually appealing and structured web pages.Here’s a breakdown of different types of selectors in CSS:

Element Selector (element):

The Element Selector in CSS targets all instances of a specific HTML element type. It applies styles universally to every occurrence of that element throughout the HTML document. For example, to style all <h5> elements with a specific co;or, you would use:

CSS Code

														
h5 {
    color : red;
    /* other styles */
}

Class Selector (.class):

The Class Selector in CSS targets elements that have a specific class attribute. It allows you to apply styles to multiple elements across your HTML document without affecting other elements that don't share the same class. For example, to style all elements with the class "pba":

CSS Code

														
.pba {
    color: red;
    font-weight: bold;
    /* other styles */
}

In HTML, you would apply this class to elements like this:

HTML Code

														
<!DOCTYPE html>
<html>
<head>
	<title></title>
</head>
<body>
	<h4 class="pba">PBA INSRITUTE</h4>

</body>
</html>

Class selectors are versatile and widely used for styling groups of elements that share common characteristics or need a specific visual treatment.

ID Selector (#id):

The ID Selector in CSS targets a single, unique element in an HTML document based on its ID attribute. Unlike classes, IDs must be unique within the document, making this selector suitable for styling a specific element uniquely. Here's how you would use an ID selector:

CSS Code

														
#pba {
    background-color: #f0f0f0;
    padding: 10px;
    /* other styles */
}

HTML Code

														
<div id="pba">
    <h1>PBA INSTOTUTE</h1>
    <p>Welcome to PBA INSTOTUTE!</p>
</div>

IDs are typically used for elements that require distinct styling or functionality, such as headers, footers, or unique sections within a webpage. It's important to note that IDs should be used sparingly to maintain clarity and avoid CSS specificity issues.

Conclusion :

In conclusion,CSS selectors offer powerful ways to target and style elements in HTML documents. From basic element selectors (p {}) to advanced ones like attribute selectors ([type="text"] {}), they provide flexibility in applying styles based on element type, class, ID, attributes, and relationships. Understanding and using selectors effectively ensures precise control over design and layout, facilitating the creation of visually appealing and responsive web pages.
