问题描述

嗨伙计们,


我在一些页面中发现了这个:


< td style =" border-bottom:1px solid #000000; border-left:1px solid

#000000; background-color:#4080A0; font-weight:bold;颜色:#000000;"

class =" myclass">


我从未见过同一元素中使用的样式和类。

常见吗?哪个胜利?会发生什么?


对于它的价值,类myclass实际上没有被定义。

Hi folks,

I found this in some pages:

<td style="border-bottom: 1px solid #000000; border-left: 1px solid
#000000; background-color:#4080A0;font-weight: bold; color: #000000;"
class="myclass">

I''ve never seen both style and class used in the same element. Is the
common? Which wins? What happens?

For what it''s worth, the class myclass was not actually defined.

样式属性比外部样式表具有更高的特异性。

重新设计正在进行中:

微软宣布IE已经死亡(所以升级):



The style attribute has a higher specificity then external style sheets.

这就是级联的地方。规则发挥作用。 ID比CL $更重,但本地定义的样式比链接更重要

样式表,定义的样式的最后一个实例覆盖以前的

实例等等。

This is where the "cascade" rules come into play. IDs have more weight than
CLASSes, but locally-defined styles have more weight than linked
stylesheets, the last instance of style defined overrides a previous
instance, etc., etc.

不一定,ID''在外部样式表中具有比内联样式更高的b $ b特异性。

Not necessarily, ID''s in an external stylesheet have a higher
specificity than an inline style.
