css - 在我的文本框中添加搜索图标

Question

我想做的是:在文本框右侧添加搜索图标

我在 [css] 中使用的代码是这样的:

.tb4 {
background: #3f4c6b; /* Old browsers */
background: -moz-linear-gradient(top,  #3f4c6b 0%, #3f4c6b 100%); /* FF3.6+ */
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#3f4c6b), color-stop(100%,#3f4c6b)); /* Chrome,Safari4+ */
background: -webkit-linear-gradient(top,  #3f4c6b 0%,#3f4c6b 100%); /* Chrome10+,Safari5.1+ */
background: -o-linear-gradient(top,  #3f4c6b 0%,#3f4c6b 100%); /* Opera 11.10+ */
background: -ms-linear-gradient(top,  #3f4c6b 0%,#3f4c6b 100%); /* IE10+ */
background: linear-gradient(to bottom,  #3f4c6b 0%,#3f4c6b 100%); /* W3C */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#3f4c6b', endColorstr='#3f4c6b',GradientType=0 ); /* IE6-9 */
 background: url(web.png) top right no-repeat;
 padding: 4px 4px 4px 22px;
 height: 18px;
 border: 1px solid #494949;
}

我得到的结果是:

• 我的主文件夹中确实有 web.png。 *

Answer 1

渐变和背景图像会发生冲突。尝试:

.tb4 {
  /* as above but without the background line for web.png */
  position: relative; /* and add this line */
}
.tb4:after { /* and this rule */
  content: "";
  display: block;
  width: 20px; /* change dimensions as needed to match image */
  height: 20px;
  background: url(web.png) top right no-repeat;
  position: absolute;
  top: 0;
  right: 0;
}
