The <button> tag is used to create clickable buttons on the web page. The difference between these elements and buttons created with the <input> tag is that you can place the content (images or text) inside the <button>.

Use the <input> element to define a button within HTML form, as browsers display the content of the <button> tag differently.

Syntax

The <button> tag comes in pairs. The content is written between the opening (<button>) and closing (</button>) tags.

Example of the HTML <button> tag:

<!DOCTYPE html> <html> <head> <title>Title of the document</title> </head> <body> <h1>Here will be our button</h1> <button type="button">Click</button> </body> </html> Try it Yourself »

Using CSS styles

You can apply CSS styles to the <button> tag to change the appearance of the button, its size, color, text font, and so on.

Example of the <button> tag with CSS styles:

<!DOCTYPE html> <html> <head> <title>Title of the document</title> </head> <body> Ordinary button <button type="button">Add to the recycle bin</button> <hr /> Button with red text <button type="button" style="color: red;"><b>HTML Book </b></button> <hr /> Button with increased font size <button type="button" style="font: bold 14px Arial;">Download the book </button><br /> </body> </html> Try it Yourself »

How to add alt text to a button with an image?

To add alt text to a button with an image, you can use the alt attribute. Here is an example:

<button type="button"> <img src="button-image.png" alt="Button Label"> </button>

In this example, the alt attribute has been added to the img element inside the button element. The value of the alt attribute should be a short description of the image, which will be read by screen readers in place of the image itself.
