当使用bootstrap激活时,如何改变按钮的颜色?

问题描述:

我使用的是bootstrap 3.当我点击按钮时,我想改变按钮的颜色。我的意思是按钮应该是不同的颜色,当它被选择。我如何使用css?

I am using bootstrap 3. I want to change button color when I click on button.I mean button should be in different color when it is selected. How can I do this using css?

我的代码是:

<div class="col-sm-12" id="">
    <button type="submit" class="btn btn-warning" id="1">Button1</button>
    <button type="submit" class="btn btn-warning" id="2">Button2</button>
</div>


影响。在您的情况下,您可以使用

CSS has different pseudo selector by which you can achieve such effect. In your case you can use


:活动:如果您只想在按钮被点击时不想坚持。

:active : if you want background color only when the button is clicked and don't want to persist.

:focus :如果您想要背景颜色,直到焦点在按钮上。

:focus: if you want background color untill the focus is on the button.



button:active{
    background:olive;
}

button:focus{
    background:olive;
}
