?? HTML Tips: Global vs. Custom Attributes ??

Ever wondered how websites store extra data or make elements interactive? Let’s break it down:

Global Attributes

These are like the default settings—you can use them on ANY HTML element.

?? Examples:

id: A unique name for an element (like a label).

• html

Copy code

<div id="main-header"></div>        

class: Group elements for CSS or JavaScript.        

• html

Copy code

<p class="highlight">Styled Text</p>        

title: A little tooltip when you hover.        

• html

Copy code

<img src="photo.jpg" title="Cute Puppy">        

Custom Attributes (data-*)

These are your DIY attributes—add them to store extra data.

?? Examples:

Track a user’s ID:

• html

Copy code

<button data-user-id="007">Click Me</button>        

Save a theme preference:

• html

Copy code

<input type="checkbox" data-theme="dark" checked>        

?? Why use them?

You can access these custom attributes in JavaScript for extra functionality:

javascript

Copy code

const userId = document.querySelector('[data-user-id]').dataset.userId;        

console.log(userId); // Outputs: 007
