The editor will share with you how to use CSS:focus pseudo-classes. I hope you will get something after reading this article. Let's discuss it together.

By default, the size of the element depends on the size of the maximum text. However, sometimes when the user tries to select an option (that is, focus), it is useful to set the fixed width to the selection box and increase its size back to its original size.

The following example shows how to achieve this effect using pure CSS:

Try this code for example »

Increase Select Box Size on Focus

Select {

Width: 150px

Margin: 10px

}

Select:focus {

Min-width: 150px

Width: auto

}

Choose

This option is large

This option is very large

This option is very very large

This option is very very very large
