文档中的 inline-styles具有最高的优先级,例如,如果希望将 div元素的颜色更改为 blue,但是将 inline style的 color属性设置为 red
<div style="font-size: 18px; color: red;">
Hello World, How Can I Change The Color To Blue?
</div>
div {
color: blue;
/* This Won't Work, As Inline Styles Have Color Red And As
Inline Styles Have Highest Priority, We Cannot Over Ride
The Color Using An Element Selector */
}
<div style="font-size: 18px; color: red;">
Hello World, How Can I Change The Color To Blue?
</div>
div {
color: blue !important;
/* This will Work */
}
但如果你有
<div style="font-size: 18px; color: red !important;">
Hello World, How Can I Change The Color To Blue?
</div>
div {
color: blue !important;
/* This Isn't Working */
}
