HTML空格怎么显示？如何插入特殊字符？

<p><a style=”color:#f60; text-decoration:underline;” title=”浏览器” href=”https://www.php.cn/zt/16180.html” target=”_blank”>浏览器</a>默认将连续空格折叠为一个，因此需使用 等html实体显示多个空格；2. 特殊字符如©、®应通过命名实体（如©、®）或数字实体（如©、®）插入，以确保正确显示且避免语法冲突；3. 更多空格类型包括 （全角空格）、 （半角空格）、 （细空格），用于不同排版需求；4. 精确保留换行与空格可使用<a style=”color:#f60; text-decoration:underline;” title=”css” href=”https://www.php.cn/zt/15716.html” target=”_blank”>css</a>的white-space: pre或pre-wrap属性；5. 所有html特殊符号均推荐用实体形式插入，保障跨平台兼容性与渲染准确性。</p><p><img src=”https://img.php.cn/upload/article/001/221/864/175550736586756.jpg” alt=”HTML空格怎么显示？如何插入特殊字符？”></p><p>HTML中显示单个空格，通常直接敲击键盘上的空格键就行了。但要注意，如果你连续敲好几个空格，浏览器默认只会把它们显示成一个。如果真的想显示多个连续的空格，那就得用到特殊的HTML实体，最常见的就是<div class=”code” style=”position:relative; padding:0px; margin:0px;”><pre class=”brush:php;toolbar:false;”> </pre>

</div>。至于如何插入像版权符号©、注册商标®这些特殊字符，核心也是通过HTML实体来完成，可以是命名实体（比如<div class=”code” style=”position:relative; padding:0px; margin:0px;”><pre class=”brush:php;toolbar:false;”>©</pre>

</div>）或者数字实体（比如<div class=”code” style=”position:relative; padding:0px; margin:0px;”><pre class=”brush:php;toolbar:false;”>©</pre>

</div>）。</p><h3>解决方案</h3><p>说实话，HTML处理空格这事儿，初学者往往会有点懵。你可能在代码里敲了一大串空格，刷新页面一看，咦？怎么就剩一个了。这是因为HTML浏览器在渲染内容时，有一个“空白字符折叠”的机制。它会把连续的空格、制表符（tab）、换行符（newline）都当作一个单一的空格来处理。</p><p>所以，要显示多个连续的空格，最直接、最常用的办法就是使用<strong>不间断空格实体</strong>：<div class=”code” style=”position:relative; padding:0px; margin:0px;”><pre class=”brush:php;toolbar:false;”> </pre>

</div>。每写一个<div class=”code” style=”position:relative; padding:0px; margin:0px;”><pre class=”brush:php;toolbar:false;”> </pre>

</div>，就代表一个标准的空格，而且它还有一个额外的特性，就是“不间断”，意味着这个空格不会在行尾被浏览器拆开。比如，你想在两个单词之间留出三个空格的距离，就写成 <div class=”code” style=”position:relative; padding:0px; margin:0px;”><pre class=”brush:php;toolbar:false;”>Word1 Word2</pre>

</div>。</p><p><span>立即学习</span>“<a href=”https://pan.quark.cn/s/cb6835dc7db1″ style=”text-decoration: underline !important; color: blue; font-weight: bolder;” rel=”nofollow” target=”_blank”>前端免费学习笔记（深入）</a>”；</p><p>当然，如果你需要更精细的空格控制，或者想保留文本中原有的所有空白格式（比如显示代码块），那就得请出CSS的<div class=”code” style=”position:relative; padding:0px; margin:0px;”><pre class=”brush:php;toolbar:false;”>white-space</pre>

</div>属性了。设置<div class=”code” style=”position:relative; padding:0px; margin:0px;”><pre class=”brush:php;toolbar:false;”>white-space: pre;</pre>

</div>或者<div class=”code” style=”position:relative; padding:0px; margin:0px;”><pre class=”brush:php;toolbar:false;”>white-space: pre-wrap;</pre>

</div>，能让浏览器完全按照你在HTML源码里写的那样去显示空格和换行。这在展示诗歌、代码或者任何需要精确排版的内容时，简直是神器。</p><p>至于插入特殊字符，比如那些键盘上没有的符号，或者HTML语法里有特殊含义的字符（比如<div class=”code” style=”position:relative; padding:0px; margin:0px;”><pre class=”brush:php;toolbar:false;”><</pre>

</div>、<div class=”code” style=”position:relative; padding:0px; margin:0px;”><pre class=”brush:php;toolbar:false;”>></pre>

</div>、<div class=”code” style=”position:relative; padding:0px; margin:0px;”><pre class=”brush:php;toolbar:false;”>&</pre>

</div>），我们同样依赖<strong>HTML实体</strong>。HTML实体有两种形式：</p><ol><li><p><strong>命名实体（Named Entities）</strong>：以<div class=”code” style=”position:relative; padding:0px; margin:0px;”><pre class=”brush:php;toolbar:false;”>&</pre>

</div>开头，后面跟着一个字符名称，以<div class=”code” style=”position:relative; padding:0px; margin:0px;”><pre class=”brush:php;toolbar:false;”>;</pre>

&amp;amp;amp;amp;amp;amp;amp;amp;lt;/div&amp;amp;amp;amp;amp;amp;amp;amp;gt;结尾。比如：&amp;amp;amp;amp;amp;amp;amp;amp;lt;/p&amp;amp;amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;amp;amp;lt;ul&amp;amp;amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;amp;amp;lt;li&amp;amp;amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;amp;amp;lt;div class=”code” style=”position:relative; padding:0px; margin:0px;”&amp;amp;amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;amp;amp;lt;pre class=”brush:php;toolbar:false;”&amp;amp;amp;amp;amp;amp;amp;amp;gt;<&amp;amp;amp;amp;amp;amp;amp;amp;lt;/pre&amp;amp;amp;amp;amp;amp;amp;amp;gt;

&amp;amp;amp;amp;amp;amp;amp;amp;lt;/div&amp;amp;amp;amp;amp;amp;amp;amp;gt;就是你发出这个指令的“口令”。它不仅代表一个空格，还“固执”地不会被折叠，也不会在行尾断开，这在某些需要精确排版（比如列表项前的缩进，或者特定文本间的间距）的场景下非常有用。&amp;amp;amp;amp;amp;amp;amp;amp;lt;/p&amp;amp;amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;amp;amp;lt;p&amp;amp;amp;amp;amp;amp;amp;amp;gt;当然，如果你是想展示一段代码或者诗歌，希望它完全保留原始的格式，包括所有的空格和换行，那么CSS的&amp;amp;amp;amp;amp;amp;amp;amp;lt;div class=”code” style=”position:relative; padding:0px; margin:0px;”&amp;amp;amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;amp;amp;lt;pre class=”brush:php;toolbar:false;”&amp;amp;amp;amp;amp;amp;amp;amp;gt;white-space&amp;amp;amp;amp;amp;amp;amp;amp;lt;/pre&amp;amp;amp;amp;amp;amp;amp;amp;gt;

&amp;amp;amp;amp;amp;amp;amp;amp;lt;/div&amp;amp;amp;amp;amp;amp;amp;amp;gt;属性才是真正的解决方案。比如给一个&amp;amp;amp;amp;amp;amp;amp;amp;lt;div class=”code” style=”position:relative; padding:0px; margin:0px;”&amp;amp;amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;amp;amp;lt;pre class=”brush:php;toolbar:false;”&amp;amp;amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;amp;amp;lt;div&amp;amp;amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;amp;amp;lt;/pre&amp;amp;amp;amp;amp;amp;amp;amp;gt;

&amp;amp;amp;amp;amp;amp;amp;amp;lt;/div&amp;amp;amp;amp;amp;amp;amp;amp;gt;或者&amp;amp;amp;amp;amp;amp;amp;amp;lt;div class=”code” style=”position:relative; padding:0px; margin:0px;”&amp;amp;amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;amp;amp;lt;pre class=”brush:php;toolbar:false;”&amp;amp;amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;amp;amp;lt;pre class=”brush:php;toolbar:false;”&amp;amp;amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;amp;amp;lt;/pre&amp;amp;amp;amp;amp;amp;amp;amp;gt;

&amp;amp;amp;amp;amp;amp;amp;amp;lt;/div&amp;amp;amp;amp;amp;amp;amp;amp;gt;标签设置&amp;amp;amp;amp;amp;amp;amp;amp;lt;div class=”code” style=”position:relative; padding:0px; margin:0px;”&amp;amp;amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;amp;amp;lt;pre class=”brush:php;toolbar:false;”&amp;amp;amp;amp;amp;amp;amp;amp;gt;white-space: pre;&amp;amp;amp;amp;amp;amp;amp;amp;lt;/pre&amp;amp;amp;amp;amp;amp;amp;amp;gt;

&amp;amp;amp;amp;amp;amp;amp;amp;lt;/div&amp;amp;amp;amp;amp;amp;amp;amp;gt;，浏览器就会“听话”地按照你源代码里的样子来显示文本，包括每一个空格和每一次换行。这比手动敲一堆&amp;amp;amp;amp;amp;amp;amp;amp;lt;div class=”code” style=”position:relative; padding:0px; margin:0px;”&amp;amp;amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;amp;amp;lt;pre class=”brush:php;toolbar:false;”&amp;amp;amp;amp;amp;amp;amp;amp;gt; &amp;amp;amp;amp;amp;amp;amp;amp;lt;/pre&amp;amp;amp;amp;amp;amp;amp;amp;gt;

&amp;amp;amp;amp;amp;amp;amp;amp;lt;/div&amp;amp;amp;amp;amp;amp;amp;amp;gt;要高效和优雅得多。&amp;amp;amp;amp;amp;amp;amp;amp;lt;/p&amp;amp;amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;amp;amp;lt;h3&amp;amp;amp;amp;amp;amp;amp;amp;gt;除了 ，还有哪些常用的HTML空格实体？它们有什么&amp;amp;amp;amp;amp;amp;amp;amp;lt;a style=”color:#f60; text-decoration:underline;” title=”区别” href=”https://www.php.cn/zt/27988.html” target=”_blank”&amp;amp;amp;amp;amp;amp;amp;amp;gt;区别&amp;amp;amp;amp;amp;amp;amp;amp;lt;/a&amp;amp;amp;amp;amp;amp;amp;amp;gt;？&amp;amp;amp;amp;amp;amp;amp;amp;lt;/h3&amp;amp;amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;amp;amp;lt;p&amp;amp;amp;amp;amp;amp;amp;amp;gt;是的，除了最常见的&amp;amp;amp;amp;amp;amp;amp;amp;lt;div class=”code” style=”position:relative; padding:0px; margin:0px;”&amp;amp;amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;amp;amp;lt;pre class=”brush:php;toolbar:false;”&amp;amp;amp;amp;amp;amp;amp;amp;gt; &amp;amp;amp;amp;amp;amp;amp;amp;lt;/pre&amp;amp;amp;amp;amp;amp;amp;amp;gt;

&amp;amp;amp;amp;amp;amp;amp;amp;lt;/div&amp;amp;amp;amp;amp;amp;amp;amp;gt;，HTML还提供了一些其他类型的空格实体，它们的主要区别在于所占据的宽度不同。理解这些差异，能让你在排版时有更多的选择，尤其是在需要微调文本间距的时候。&amp;amp;amp;amp;amp;amp;amp;amp;lt;/p&amp;amp;amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;amp;amp;lt;ol&amp;amp;amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;amp;amp;lt;li&amp;amp;amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;amp;amp;lt;p&amp;amp;amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;amp;amp;lt;strong&amp;amp;amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;amp;amp;lt;div class=”code” style=”position:relative; padding:0px; margin:0px;”&amp;amp;amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;amp;amp;lt;pre class=”brush:php;toolbar:false;”&amp;amp;amp;amp;amp;amp;amp;amp;gt; &amp;amp;amp;amp;amp;amp;amp;amp;lt;/pre&amp;amp;amp;amp;amp;amp;amp;amp;gt;
