White-space: pre fails to cause code highlighting to be inconsistent. How to solve it?

Safari browser code highlighting compatibility issues and solutions

In web development, in order to keep the original format of the code snippet (including indentation and spaces), we usually use <code>white-space: pre CSS attribute. However, in some cases, Safari browsers have compatibility issues with handling of this property, causing the code to appear incorrectly. This article analyzes this problem and provides solutions.

Problem description:

When rendering code high-scaling fragments using <code>white-space: pre , Safari browser may experience compatibility issues. For example, the following code:

 <code class="html"> import { definecomponent } from '#imports' ;预期输出应与以下代码一致： ```javascript import { definecomponent } from '#imports';</code>

However, in Safari browser, line breaks may occur with <code>'#imports' . After testing, it was found that when the text content was<code><code>标签包裹时， <code>white-space: pre属性失效。而使用简单的<code>

标签则不会出现此问题。

Solution:

In order to solve the compatibility problem under Safari browser, it is recommended to use a more comprehensive <code>white-space attribute setting and combine <code>word-wrap attribute:

 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'); /* Older Mozilla */
}

This CSS code provides compatibility support for different browsers, ensuring that the code can correctly display indents and spaces, even if the text content is<code><code>标签包裹。 <code>word-wrap: break-word;属性允许长单词或文本自动换行，避免因过长而导致布局问题。 请注意， <code>-moz-binding通常用于较旧的Mozilla浏览器，现代浏览器可能不需要此行代码。 如果仍然存在问题，请检查是否存在其他CSS样式冲突。
