HTML Tag
The tag is used to create clickable buttons on the web page. The difference between these elements and buttons created with the tag is that you can place the content (images or text) inside the .
Use the element to define a button within HTML form, as browsers display the content of the tag differently.

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.

In this example, the a element has been added around the button element, and the href attribute has been set to the URL you want to link to. When the user clicks on the button, they will be taken to the linked URL.
CSS Tooltip
A tooltip is often used to specify extra information about something when the user moves the mouse pointer over an element:
Basic Tooltip
Create a tooltip that appears when the user moves the mouse over an element:
Example
/* Tooltip text */
.tooltip .tooltiptext visibility: hidden;
width: 120px;
background-color: black;
color: #fff;
text-align: center;
padding: 5px 0;
border-radius: 6px;
/* Position the tooltip text — see examples below! */
position: absolute;
z-index: 1;
>
/* Show the tooltip text when you mouse over the tooltip container */
.tooltip:hover .tooltiptext visibility: visible;
>
Example Explained
HTML: Use a container element (like ) and add the «tooltip» class to it. When the user mouse over this , it will show the tooltip text.
The tooltip text is placed inside an inline element (like ) with class=»tooltiptext» .
CSS: The tooltip class use position:relative , which is needed to position the tooltip text ( position:absolute ). Note: See examples below on how to position the tooltip.
The tooltiptext class holds the actual tooltip text. It is hidden by default, and will be visible on hover (see below). We have also added some basic styles to it: 120px width, black background color, white text color, centered text, and 5px top and bottom padding.
The CSS border-radius property is used to add rounded corners to the tooltip text.
The :hover selector is used to show the tooltip text when the user moves the mouse over the with class=»tooltip» .
Positioning Tooltips
In this example, the tooltip is placed to the right ( left:105% ) of the «hoverable» text (). Also note that top:-5px is used to place it in the middle of its container element. We use the number 5 because the tooltip text has a top and bottom padding of 5px. If you increase its padding, also increase the value of the top property to ensure that it stays in the middle (if this is something you want). The same applies if you want the tooltip placed to the left.
