In HTML, you can use CSS attributes opacity To set the transparency of the element. This attribute accepts a value between 0 and 1, where 0 means completely transparent and 1 means completely opaque.

The following is an example of how to set the transparency of an element to 50%:

In this example, by using the style Specified in the attribute opacity: 0.5 , will <div> The transparency of the element is set to 50%.

Note that using the opacity Attributes affect everything inside an element, including text and child elements.
