How can I apply CSS on all buttons which are present in that page?
提问by ashu
I have created a CSS style class:
我创建了一个 CSS 样式类：
.btn {
color:#050;
font: bold 84% 'trebuchet ms',helvetica,sans-serif;
background-color:#fed;
border:1px solid;
border-color: #696 #363 #363 #696;
}
How can I apply this CSS style class to all buttons which are present in the page without adding class="btn"to every button?
如何将此 CSS 样式类应用于页面中存在的所有按钮而不添加class="btn"到每个按钮？

If your buttons are <input type="button">or submit, then this should do it:
如果您的按钮是<input type="button">或提交，那么应该这样做：
input[type="button"], input[type="submit"] {
color:#050;
font: bold 84% 'trebuchet ms',helvetica,sans-serif;
background-color:#fed;
border:1px solid;
border-color: #696 #363 #363 #696;
}
Otherwise, if your buttons are <button>:
否则，如果您的按钮是<button>：
button {
color:#050;
font: old 84% 'trebuchet ms',helvetica,sans-serif;
background-color:#fed;
border:1px solid;
border-color: #696 #363 #363 #696;
}
To grab all three kinds of buttons:
抓取所有三种按钮：
button, input[type="button"], input[type="submit"] {
color:#050;
font: bold 84% 'trebuchet ms',helvetica,sans-serif;
background-color:#fed;
border:1px solid;
border-color: #696 #363 #363 #696;
}

If you don't want to explicitly set all the styles, but want to use the styles already defined in some pre-existing class (for example the bootstrap btn-default class), you could do something like this:
如果您不想显式设置所有样式，而是想使用某些预先存在的类（例如 bootstrap btn-default 类）中已经定义的样式，您可以执行以下操作：
<script>
$("button").addClass("btn-default");
</script>
In my case this was what I was looking for, although I'm sure there is some sort of caveat about doing it this way, or you'd expect it was something doable directly from CSS.
在我的情况下，这就是我正在寻找的东西，尽管我确信这样做会有一些警告，或者你会期望它可以直接从 CSS 中实现。

just a note
只是一个笔记
input[type="button"]
isn't going to work on old browsers like IE6. If that's a problem you will unfortunately need to add your class to each item.
不适用于像 IE6 这样的旧浏览器。如果这是一个问题，您将不幸需要将您的课程添加到每个项目中。
