transparent linear-gradient applied to text - bug in Safari

Question

I am trying to fade the white text of a paragraph on an image background from white to transparent. I have it working in Chrome and Firefox but can't seem to get it working in Safari.

In my example you'll notice that the text does not display in Safari but if you highlight the text it will appear. JSFiddle here: https://jsfiddle.net/ngaffer/fgxbfoL4/5/

Image of the desired effect

Answer 1

I would avoid doing this as the support is still not there yet. but...

I am able to achieve the desired effect by adding:

-webkit-mask-image: linear-gradient(to top, rgba(0, 0, 0, 0)1em, rgba(0, 0, 0, 1)); 

to the text class.

You can control the amount of fade by increasing / decreasing the 1em after the first color in the gradient

Tested and working on Chrome 59 and FF 54 - with the -webkit prefix. I don't have Safari but it should be supported.

This won't work on IE or Edge but still...89% support is not too shabby.

section {
  background-color: #111;
  display: block;
  overflow: hidden;
  color: #fff;
}

.hideContent {
  -webkit-mask-image: linear-gradient(to top, rgba(0, 0, 0, 0)1em, rgba(0, 0, 0, 1));
  height: 100px;
}
