The “id” attribute in HTML (Hypertext Markup Language) is used to uniquely identify an element within a web page. It is an attribute that can be added to most HTML elements, such as headings, paragraphs, images, links, forms, etc.
The value of the “id” attribute should be unique within the page. This means that no two elements within the same page should have the same “id” value. The value of the “id” attribute is usually a string of letters, numbers, and underscores.
The “id” attribute is often used in conjunction with CSS (Cascading Style Sheets) and JavaScript to manipulate and style specific elements on a web page. For example, using CSS, you can style a specific element with a particular “id” value by targeting it with the “#” symbol followed by the “id” value. In JavaScript, you can use the “getElementById” method to retrieve an element with a specific “id” value and perform actions on it.
Here’s an example of how the “id” attribute can be used in HTML:
<p id="intro">This is the introduction paragraph.</p>
In this example, the “id” attribute is added to the paragraph element with a value of “intro”. This allows the element to be uniquely identified within the page and targeted with CSS or JavaScript for styling or manipulation.
