我制作一些css按钮,我想在文本前添加一个图标,"按钮文字".

但我不知道我应该怎么做......

HTML <div class="btn btn_red"><a href="#">Crimson</a><span></span></div>

CSS

body {
    margin: 0;
    padding: 10px;
    font-family: Verdana, Arial, Helvetica, sans-serif;
    font-size: 14px;
}
/* Glassy Buttons */
.btn {
    float: left;
    clear: both;
    background: url(imgs/button_left.png) no-repeat;
    padding: 0 0 0 10px;
    margin: 5px 0;
}
.btn a{
    float: left;
    height: 40px;
    background: url(imgs/button_middle.png) repeat-x left top;
    line-height: 40px;
    padding: 0 10px;
    color: #fff;
    font-size: 1em;
    text-decoration: none;
}
.btn span {
    background: url(imgs/button_right.png) no-repeat;
    float: left;
    width: 10px;
    height: 40px;
}
.btn_gray {background-color: #808080;}
.btn_green { background-color: #ADFF2F;}
.btn_blue {background-color: #0000CD;}
.btn_red {background-color: #DC143C;}

Answer 1

您可以在链接之前添加一个特定类的跨度,如下所示:

<div class="btn btn_red"><span class="icon"></span><a href="#">Crimson</a><span></span></div>

然后给出一个特定的宽度和背景图像,就像你使用按钮本身一样.

.btn span.icon {
    background: url(imgs/icon.png) no-repeat;
    float: left;
    width: 10px;
    height: 40px;
}

我不是CSS大师,但我认为这应该有用.

以下是使用font-awesome库可以执行的操作.

button.btn.add::before {
  font-family: fontAwesome;
  content: "\f067\00a0";
}

button.btn.edit::before {
  font-family: fontAwesome;
  content: "\f044\00a0";
}

button.btn.save::before {
  font-family: fontAwesome;
  content: "\f00c\00a0";
}

button.btn.cancel::before {
  font-family: fontAwesome;
  content: "\f00d\00a0";
}
