图片排满一行。左右两端无间隙。
<style type="text/css"> .img_abc{float:left;width:30%;margin-left:5%;} .img_abc:first-child{margin-left:0} .body92{margin-left:4%;margin-right:4%;} </style> <div class="body92"> <img src="1408587440309.png" class="img_abc"> <img src="1408587445662.png" class="img_abc"> <img src="1408587456115.png" class="img_abc"> </div>
用图片替代:文件上传按钮
<div class="file-box"> <input type="file" id="focusPic" name="focusPic" class="fileupload-hidden" onchange="showCurrentImg('focusImg')"> <img src="http://images.csdn.net/20140820/up.jpg" class="img-file-btn"> </div> <style type="text/css"> .file-box{position: relative;width: 120px;height: 90px;overflow: hidden;border: 1px solid #F0F0F0;} .fileupload-hidden {width: 120px;height: 90px;position: absolute;left: 0;top: 0;right: 0;bottom: 0;z-index: 2;margin: 0;padding: 0;font-size: 1000px;opacity: 0;filter: alpha(opacity=0);} .img-file-btn {position: absolute;left: 0;top: 0;right: 0;bottom: 0;width: 100%;height: 100%;z-index: 1;} </style>
