The code highlighting problem under Safari browser: What is the reason for the invalidation of the ``` tag combined with `white-space: pre` attribute?
Safari browser code highlighting problem and solution
In web development, in order to clearly display code snippets and retain their formatting and indentation, it is usually used<code><code>标签结合<code><pre class="brush:php;toolbar:false"></pre>标签,并设置<code>white-space: pre CSS属性。然而,Safari浏览器在处理包含<script>标签且文本较长的代码片段时,可能会忽略<code>white-space: pre属性,导致代码换行,破坏原有格式。</script>
例如,如下代码在Safari浏览器中,“#imports”可能会被换行显示:
<script> import { definecomponent } from '#imports'; </script>And simple<code><div> This problem will not occur with the tag:<pre class="brush:php;toolbar:false"><div> hello world</div> // Pre settings can ensure that no line breaks
This means that when the text is labeled (e.g. <script>)包裹时,<code>white-space: pre的有效性会受到影响。</script>
为了解决这个问题,建议使用以下CSS代码:
pre { white-space: pre-wrap; /* CSS3 */ white-space: -moz-pre-wrap; /* Mozilla, since 1999 */ white-space: -pre-wrap; /* Opera 4-6 */ white-space: -o-pre-wrap; /* Opera 7 */ word-wrap: break-word; /* Internet Explorer 5.5 */ -moz-binding: url('./wordwrap.xml#wordwrap'); /* 需要配合wordwrap.xml文件使用 */ }
这段代码使用了多种<code>white-space属性值和<code>word-wrap属性,以确保跨浏览器兼容性,并允许文本在必要时换行,从而避免Safari浏览器中<code>white-space: pre失效的问题。请注意,<code>-moz-binding部分需要配合相应的<code>wordwrap.xml文件,本文未提供该文件内容。 使用<code>pre-wrap允许文本换行,同时保留空格和换行符。
