我已经使用自己的bootstrap创建了一个Image Uploader，但是当我在我的页面<hr/>中使用它的bootstrap.css标签和其他标签css受到影响并且没有提供正确的输出，因为我和＃39;设计。这是 My Form ，其中我需要应用此 Image Uploader 。但是当我将这个Image Uploader脚本及其css插入或复制到My Form in Image部分时。它扰乱了我的整个css，只使用bootstrap css并提交表单，甚至点击清除按钮。在我混合My Form＆amp; Image Uploader我得到了这个输出，下面给出了代码，片段，这是 JSFIDDLE 。我添加Image uploader后，请检查我的表单和表单，它会扰乱我的css文件，甚至不会显示我的图像预览。我不知道我哪里出错了。
$("#ImageUploader").submit(function (e) {
"use strict";
var fileUpload = $("#file")[0].files,
fileCount = $("#file")[0].files.length;
if (parseInt(fileCount) > 5) {

e.preventDefault();

答案 0 :(得分：1)
如sanjeev所述，首先是在自定义CSS文件之前链接bootstrap.css文件。如果Bootstrap的某些样式正在影响您的样式，那么请更具体地给出元素类和样式。
我注意到您的CSS定位的是像td这样的普通元素，因此请提供td个，tr的类，并将它们定位在您的CSS中，如td.classname {properties}。
或者，为父级table / div提供一个类，并将这些元素指定为父级的子级，即table.classname tr {properties}。
答案 1 :(得分：1)
您可以按如下方式查看文件：
css属性按顺序呈现，您可以渲染这样的文件：
<link rel="stylesheet" href="common/bootstrap/css/bootstrap.css" />
<link rel="stylesheet" href="common/css/own.css" />
您可以使用“！important”确保您已实施css属性，如下所示：
.important-css {
color: red !important;
}
