好吧,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>


而且我认为它可能已经损坏了一些东西!我所有其他代码行都可以正常运行,但是这一行!我以为它会使每个默认的新段落变成16pt黑色...但是它不能让我改变颜色。

.need1类未正确调用,并显示为黑色16pt的先前设置,而不是居中的24pt红色粗体文本的.need1类。

而且,Jfiddler一直告诉我

</P>


因为关闭是不适当的,所以我将它们移开了,但我应该放回去吗?我已经尝试过两种方法,但都不能解决问题。

    <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}

html - CSS样式类没有改变-LMLPHP

最佳答案

尝试使用!重要





 P {color:black !important; font-size: 16pt !important;}




但首先您必须更正代码中的错误,例如:为什么要写“。”样式之后,则必须写“;” CSS之间的属性不是“。”
修复后的代码



 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}
