内部文字阴影，蓝色背景，白色？

Question

我有一个带框阴影的蓝色框，文字颜色为白色，如下所示：

是否可以添加内部阴影？ 像this（jsfiddle）？它不适用于文本颜色白色，就像我的例子。

body {
  /* This has to be same as the text-shadows below */
  background: #def;
}

h1 {
  font-family: Helvetica, Arial, sans-serif;
  font-weight: bold;
  font-size: 6em;
  line-height: 1em;
}

.inset-text {
  /* Shadows are visible under slightly transparent text color */
  color: rgba(10, 60, 150, 0.8);
  text-shadow: 1px 4px 6px #def, 0 0 0 #000, 1px 4px 6px #def;
}


/* Don't show shadows when selecting text */

::-moz-selection {
  background: #5af;
  color: #fff;
  text-shadow: none;
}

::selection {
  background: #5af;
  color: #fff;
  text-shadow: none;
}

Answer 1

请您检查一下是否符合要求？

body {
    /* This has to be same as the text-shadows below */
    background: #006db1;
}
h1 {
    font-family: Helvetica, Arial, sans-serif;
    font-weight: bold;
    font-size: 6em;
    line-height: 1em;
}
.inset-text {
    /* Shadows are visible under slightly transparent text color */
    color: rgba(255, 255, 255, 0.8);
    text-shadow: 1px 4px 6px #555, 0 0 0 #ddd, 1px 4px 6px #000;
}
/* Don't show shadows when selecting text */
::-moz-selection { background: #fff; color: #000; text-shadow: none; }
::selection { background: #fff; color: #000; text-shadow: none; }

Answer 2

在您的演示中，如果您希望innerShaow为白色文字。
只需设置color: rgba(255,255,255, 0.8);即可看到内部阴影。

    -webkit-background-clip: text;
    -moz-background-clip: text;
    background-clip: text;
