css - Apply a CSS class to a button

Question

I am very new to CSS, and was wondering how to apply a class to a button. For example, suppose I had this class:

.myclass
{
background-color: #ff0000;
}

How would I properly apply that to a button?
I am really new to CSS, and appreciate your help!

Answer 1

只需将按钮的class属性设置为您的 CSS 类：

<button class="myclass">Button text</button>

Answer 2

如果你使用<button>，你可以做<button class="myclass">Hello world</button>

如果你使用<input />，那么它是 <input name="hello" type="submit" value="Hello world" class="myclass" />
