CSS Tutorial : Selectors in CSS

 Title: What is CSS selectors ? - How to use ?

Introduction :

   CSS (Cascading Style Sheets) is a crucial component of web development that allows developers to control the presentation and layout of HTML documents. To apply styles to specific elements in an HTML document, CSS uses selectors. Selectors are patterns that target specific HTML elements, allowing developers to define how these elements should be styled.

CSS selectors serve as a bridge between the HTML structure and the styles that define the visual appearance of web pages. By selecting elements based on their tag names, classes, IDs, attributes, or relationships with other elements, developers can apply different styles to different parts of a web page, creating a visually appealing and consistent user interface.

In technical terms, it is known as a selector. It tells the browser on which portion of the HTML document the styling needs to be applied.

Types of Selectors : 

1. CSS Element Selector

2. CSS ID Selector

3. CSS Class Selector

1. CSS Element Selectors :

     The element selector targets all instances of a specific HTML element. It is the most straightforward type of selector and is denoted by the element's tag name. For example, p will select all <p> elements in the HTML document. It applies styles to all elements of that type uniformly.

Note- But we don’t recommend using it in proper projects as there can be multiple times the same tag used in the document. So, overlapping of rules can occur in the stylesheet.

2. CSS Id Selectors :

    The ID selector targets a single element with a specific ID attribute. It is denoted by a hash (#) followed by the ID name. For example, #heading will select the element with id="heading". IDs must be unique within an HTML document, so this selector targets a single element uniquely.

2. CSS Class Selectors :

    The class selector targets elements with a specific class attribute. It is denoted by a dot (.) followed by the class name. For example, .highlight will select all elements with class="highlight". This selector allows you to apply the same style to multiple elements, grouping them under the same class.
