How do I combined CSS text-shadow and “background-image: -webkit-gradient”

问题

I am trying to achieve a gradient + text shadow effect in Chrome/Safari using CSS text-shadow and a combination of text-shadow and background-image: -webkit-gradient, see example blw. I can only make one of the effects apply(if I add the shadow the gradient disappears. What am I doing wrong?

h1 {
font-size: 100px;
background-image: -webkit-gradient(linear, left top, left bottom, from(white), to(black));
-webkit-background-clip: text;
-webkit-text-fill-color: transparent;
text-shadow: 0 1px 1px #fff;
}

回答1:

The gradient "disappears" because the text-shadow is on a level above the background.

The text (which is transparent)
The shadow
The background.

We can work around this by copying the text and put it below the original layer, then apply the shadow there, for example:

  h1 {
    position: relative;
    font-size: 100px;
    text-align: center;
  }

  h1 div {
    background-image: -webkit-gradient(linear, left top, left bottom, from(white), to(black));
    -webkit-background-clip: text;
    -webkit-text-fill-color: transparent;
    position: absolute; 
    width: 100%;
}
  h1:after {
    text-shadow: 10px 10px 11px #fff;
    color: transparent;
  }

  #hello:after {
        content: 'Hello World';
  }

  <h1 id="hello"><div>Hello World</div></h1>

This answer is similar to the answer by @KennyTM above, except his answer has the shadow hard-coded into the CSS, which is not suitable for dynamic text such as in a CMS. Also, his method requires a separate ID for each instance, which would be very tedious if you plan to use this effect a lot. The example below uses a class instead, and allows dynamic text.

Try this:

h1 {
    position: relative;
    font-size: 100px;
    text-align: center;
}

h1 div {
    background-image: -webkit-gradient(linear, left top, left bottom, from(teal), to(black));
    -webkit-background-clip: text;
    -webkit-text-fill-color: transparent;
    position: absolute; 
    width: 100%;
}
h1:after {
    text-shadow: 2px 2px 2px #000000;
    color: transparent;
}

.gradient-shadow:after {
    content: attr(title); /* Pulls the text from the 'title' attribute to make the shadow */
}

And then in your HTML:

<h1 class="gradient-shadow" title="Hello World"><div>Hello World</div></h1>

Just make sure that the text in the <div> matches the text in the title attribute.

With some additional formatting (I used Helvetica Neue Ultralight and a dark background), you can get an effect something like this: http://cl.ly/image/2C0k0I3W271D

With no extra HTML markup or pseudo elements you can achieve this effect using the filter property and drop-shadow function. This method also works with a background image vs gradient.

h1 {
  font:54px 'Open Sans', 'Helvetica', Arial, sans-serif;
  background-image: -webkit-gradient(linear, left top, left bottom, from(#787878), to(#484848));
  -webkit-background-clip: text;
  -webkit-text-fill-color: transparent;
  -webkit-filter: drop-shadow(2px 2px #333);
          filter: drop-shadow(2px 2px #333);
}
