HTML id

Created By: chatGPT

HTML id is an attribute used to uniquely identify an element in an HTML document. Each id must be unique within the HTML page, meaning no two elements can share the same id. This is helpful for targeting elements with CSS or JavaScript. You can define an id using the id attribute in an HTML tag. Here’s how you can use it:

<div id="myElement">This is a unique element.</div>

In this example, the div element has an id of myElement. You can easily select this element with CSS and JavaScript.

/* CSS */
#myElement {
    color: blue;
    font-weight: bold;
}

For JavaScript, you can access the element using the getElementById method. This method allows you to manipulate the element dynamically.

const element = document.getElementById('myElement');
element.style.backgroundColor = 'yellow';

A best practice is to choose meaningful and descriptive ids that indicate the purpose of the element. This makes your code more readable and easier to maintain.

<input type="text" id="userName" placeholder="Enter your name">
