CSS 块引用空行

Question

CSS 块引用不要在引号中添加空行

示例：

<blockquote>
this is number 1

this is number  2
</blockquote>

这将显示如下，但 "" > "" 不会出现，只会出现空行

> this is number 1

>

> this is number 2

我希望它们的空行包含在 blockquote 中。

Answer 1

一个>是HTML中的保留字符。它用于构建标签。

需要转义，否则浏览器会认为是代码而不显示。

< 使用 <，> 使用 >。

<blockquote>
this is number 1<br>
&gt;<br><!-- with "greater than" symbol -->
this is number  2<br>
</blockquote>
<hr>
<blockquote>
this is number 1<br>
<br><!-- with just an empty line -->
this is number  2<br>
</blockquote>

5.3.2 Character entity references

Four character entity references deserve special mention since they are frequently used to escape special characters:

< represents the < sign.

> represents the > sign.

& represents the & sign.

" represents the " mark.

Authors wishing to put the < character in text should use < (ASCII decimal 60) to avoid possible confusion with the beginning of a tag (start tag open delimiter). Similarly, authors should use > (ASCII decimal 62) in text instead of > to avoid problems with older user agents that incorrectly perceive this as the end of a tag (tag close delimiter) when it appears in quoted attribute values.
