How to style the string of an tag?

Question

Is there a way to style the alt? With javascript? With pseudo attributes? like this:

This is the caption&l         


        

Answer 1

What you are trying to achieve is styling alt text when image is somehow not displayed. Alt is not an element so you can't style it directly but what you can do to achieve the desired result is by setting font-size on img element.

JSfiddle Demo

img{
  font-size: 16px;
}

.small-alt-text{
  font-size:8px;
}
.big-alt-text{
  font-size:24px;
}
