HTML attribute is a special word used within an HTML element's opening tag to provide additional information about the element itself. These attributes act like modifiers that define the element's behavior or adjust how it appears on a webpage.
For example, the <img>
element creates an image on a webpage. By itself, the <img>
tag doesn't provide any information about the image to be displayed. However, you can add an src
attribute to specify the location (source) of the image file.
Here's an example of an <img>
tag with an src
attribute:
<img src="myimage.jpg" alt="My Image Description">
In this example, the src
attribute tells the browser where to find the image file "myimage.jpg". The alt
attribute provides alternative text that describes the image, which is useful for accessibility purposes or if the image fails to load.
There are many different HTML attributes, each serving a specific purpose. Some common attributes include:

to specify the hyperlink destination.id
