Question

好的，我真的很新。几个小时前，我将样式类“P”设置为

...// <Style>
          P {color:black, font-size: 16pt;}
...// </Style>

我认为它可能已经破坏了一些东西！我的所有其他代码行都在工作但是这一行！我认为它会让每个默认的新段落都是黑色16pt ......但它不会让我改变颜色。

.need1类没有被正确调用，并显示为黑色16pt的先前设置，而不是.need1类的居中，24pt红色，粗体文本。

此外，Jfiddler一直告诉我

</P>

因为关闭是不合适所以我删除它们但我应该把它们放回去？我已经尝试了两种方式，但没有解决问题。

    <STYLE>.

            .red1 {color: #ff0000}
            .orange1 {color: }
            .blue1
            .green1
            .need1 {font-size:24pt; color:red; font-weight: bold; text-align:center}
            .need2 {font-size:16pt; color:red;}
            .want {font-size:16pt; color:orange}
            .fun {font-size:14pt; color:green}
            .cata {font-size:20pt; color:black; font-weight: bold; text-decoration:underline; text-align: left}
            .specs1 {font-size:20pt; color:blue; font-weight:bold; text-align:center; text-decoration: underline}
            .specs2 {font-size:16pt; color: blue; text-align:center}
            .head {font-size:28pt; color:purple; text-align:center;

Answer 1

在颜色后面加一个分号，你可以用逗号代替。

P {color：black，font-size：16pt;}更改为P {color：black; font-size：16pt;}

希望有所帮助！

Answer 2

第二个和第四个p标签没有匹配的结束标记与BR标签更改相同，它将起作用也删除＆＃34;。＆＃34;样式打开和关闭标记后

Answer 3

尝试使用！important

 P {color:black !important; font-size: 16pt !important;}
            .red1 {color: #ff0000}
            .orange1 {color: }
            .blue1
            .green1
            .need1 {font-size:24pt; color:red; font-weight: bold; text-align:center}
            .need2 {font-size:16pt; color:red;}
            .want {font-size:16pt; color:orange}
            .fun {font-size:14pt; color:green}
            .cata {font-size:20pt; color:black; font-weight: bold; text-decoration:underline; text-align: left}
            .specs1 {font-size:20pt; color:blue; font-weight:bold; text-align:center; text-decoration: underline}
            .specs2 {font-size:16pt; color: blue; text-align:center}
            .head {font-size:28pt; color:purple; text-align:center; 
                    text-decoration:underline; font-weight: bold}
            .ex {font-size: 18; color:black; text-align: right}

            a:link    {color:blue; background-color:transparent; text-decoration:none}
            a:visited {color:purple; background-color:transparent; text-decoration:none}
            a:hover   {color:red; background-color:transparent; text-decoration:underline}
            a:active  {color:yellow; background-color:transparent; text-decoration:underline}

但首先你必须纠正代码中的错误，例如：为什么要写＃34;。＆＃34;在风格之后，你必须写＆＃34;;＆＃34;在css之间没有属性＆＃34;。＆＃34; 修复后的代码

<P class = "head"> TEXT

<P Class = "need1"> TEXT
    <BR>TEXT <span Class = "red1">TEXT</span> TEXT

    <BR>TEXT
    <BR>

<P Class = "cata">

    <BR>TEXT = <span class= "red1">RED</span>
