In web development, in order to clearly display code snippets and retain their formatting and indentation, it is usually used<code><code>標簽結合<code><pre class="brush:php;toolbar:false"></pre>標簽,并設置<code>white-space: pre CSS屬性。然而,Safari瀏覽器在處理包含<script>標簽且文本較長的代碼片段時,可能會忽略<code>white-space: pre屬性,導致代碼換行,破壞原有格式。</script>
例如,如下代碼在Safari瀏覽器中,“#imports”可能會被換行顯示:
<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>)包裹時,<code>white-space: pre的有效性會受到影響。</script>
為了解決這個問題,建議使用以下CSS代碼:
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 */ }
這段代碼使用了多種<code>white-space屬性值和<code>word-wrap屬性,以確保跨瀏覽器兼容性,并允許文本在必要時換行,從而避免Safari瀏覽器中<code>white-space: pre失效的問題。請注意,<code>-moz-binding部分需要配合相應的<code>wordwrap.xml文件,本文未提供該文件內容。 使用<code>pre-wrap允許文本換行,同時保留空格和換行符。
