为什么boostrap类无法正确解析?

标签: html css twitter-bootstrap twitter-bootstrap-3

在我的文件中,引用了bootstrap样式。

所有类引用都默认为主要颜色。为了显示。这个test site,左上角有button,类btn btn-success,应为绿色。

默认情况下,引导程序中带有.btn的按钮为绿色,但您已在第123行的main.css中覆盖了该按钮。

您可以更改希望为蓝色的按钮类别,也可以为它们使用不同的CSS选择器。

答案 1 :(得分:1)

来自的按钮包含课程.btn以及第二个课程,在这种情况下为.btn-success,您在main.css(第123行)覆盖课程{{1}与.btn

background-color: blue;

我的建议只是改变第二类,即附加到按钮的某种事件/动作。而不是一般.btn { background-color: blue; border-radius: 4px; font-size: smaller; } (按钮)

<link rel="stylesheet" href="css/main.css" />
<link rel="stylesheet" href="css/shares.css" />

您在css / main.css中创建了.btn类,此类覆盖了bootstrap.css文件中的类

答案 3 :(得分:1)

注意:如果您使用Bootstrap作为基本样式表,这不是问题的预期解决方案!但是,这可以突出显示自定义样式表中覆盖样式的潜在问题区域。

.btn中覆盖了main.css的样式。 这是因为main.css之后加载bootstrap.css

来自Chrome DevTools:

View of CSS from page

在此图片中,您可以看到.btnmain.css的样式优先于.btn-successbuttons.less的样式(Bootstrap样式的一部分)。

您可以通过将main.css的样式表移到bootstrap.css的样式表之上来轻松更改优先级,这将使Bootstrap的样式优先于自定义样式。

以下是您的网站的外观: Main overriding Bootstrap

移动main.css后: Bootstrap overriding main
