将背景剪辑和文本填充颜色与某些伪元素结合使用时，iOS上的Safari无法显示文本 [英] Safari on iOS not displaying text when using background-clip and text-fill-color combined with some pseudo elements

问题描述

我很难解决这个谜.我创建了一个敲除文本"效果，并在h2中使用:after添加了一个分隔符.除了iOS(10.3.2)上的Safari浏览器，它在我测试过的所有内容上看起来都很棒.

I'm having a hard time solving this mystery. I have created a "knockout text" effect and added a separator using :after to a h2. It looks great on everything I've tested it on except for Safari on iOS (10.3.2).

h2.gradient {
    color: #013c65;
    font-weight: 600;
    text-transform: uppercase;
    font-size: 2em;
    line-height: 1em;
    background: linear-gradient(1deg, #800909, #332222);
    -webkit-background-clip: text;
    -webkit-text-fill-color: transparent;
    -moz-background-clip: text;
    -moz-text-fill-color: transparent;
    -ms-background-clip: text;
    -ms-text-fill-color: transparent;
    background-clip: text;
    text-fill-color: transparent;
}
h2.gradient:after {
    content: '';
    position: relative;
    display: block;
    height: .12em;
    width: 2.5em;
    background-image: linear-gradient(1deg, #800909, #332222);
    top: .5em;
}

看起来问题似乎在于将background-clip: text;，text-fill-color: transparent;和伪元素:display: block;组合在一起.

Looks like the problem seems to be with combining background-clip: text;, text-fill-color: transparent;, and with the pseudo element: display: block;.

我能够绝对定位并内联显示伪元素.目前，我已经将标头包装在<div class="special-heading">中，并在div之后添加了分隔符.

I am able to absolute position and display inline-block the pseudo element. For the time being, I've wrapped the header in <div class="special-heading"> and added separator after the div.

iOS是否会不喜欢它，或者有其他人遇到过类似的问题?我发现添加一个零宽度的空格​使其神奇地起作用.

Would there be a reason why iOS doesn't like this or has anyone else experienced similar problems? I've found that adding a zero-width space ​ magically makes it work.

但是，我认为这可能是一个错误，因为我可以偶尔在Mac上打开Web检查器的情况下使用原始方法.

I'm thinking this might be a bug, however, because I am able to get the original method working occasionally with the web inspector open on my Mac.

感谢您的想法！

推荐答案

我遇到了类似的问题，并在单独的线程中找到了替代解决方案.

I faced similar issue and found alternative solution in separate thread.

想法是将显示属性更改为内联:display: inline.不需要"HTML hacks".

The idea is to change display property to inline: display: inline. Doesn't require "HTML hacks".

尽管此修复程序可能无法满足您的布局需求，但从CSS角度来看，这是唯一对我有用的解决方案.

Although this fix might not fit your layout needs, that's the only solution that worked for me from CSS perspective.
