如何将自定义 CSS 正确添加到 Bootstrap Modal

[英]How do I properly add custom CSS to a Bootstrap Modal

 原文  2015-09-16 03:41:34  4   2    javascript/ jquery/ html/ adobe-brackets

问题描述

我正在为名为 Brackets 的文本编辑软件编写扩展，Brackets 使用 Bootstrap 来设置 Modal 和 CSS 的样式。 我正在尝试将自定义 CSS 添加到模态，以便我可以重新格式化、移动和调整模态上不同元素的大小，例如复选框和下拉菜单，使其看起来更干净。

每次我尝试使用内置标签或链接的 CSS 将 CSS 添加到模态时，模态都无法正确加载。 模态加载，然后整个屏幕上覆盖着一层不透明的黑色薄膜，模态变得无法使用。

所以我可以推断我没有正确添加 CSS，因为当我删除我添加的 CSS 时，Modal 会纠正行为。

如何向此 Bootstrap Modal 添加自定义 CSS 样式？

使用bootstrap 预定义类来设置样式和网格系统以格式化模态内的表单

您可以添加自定义 css，就像您在执行内联样式一样<p style='display: none; color: red; font-weight: bold;' id='templates_warning'>{{DOCTYPE_ALERT}}</p> <p style='display: none; color: red; font-weight: bold;' id='templates_warning'>{{DOCTYPE_ALERT}}</p> <p style='display: none; color: red; font-weight: bold;' id='templates_warning'>{{DOCTYPE_ALERT}}</p>或放置自定义选择器并将其添加到样式表中，最好添加自定义选择器，因为稍后您可以使用媒体查询根据屏幕大小调整模式内容。

例如

<p class="nodisplay" id='templates_warning'>{{DOCTYPE_ALERT}}</p>

并在样式表中

.nodisplay {
    display: none;
    color: red;
    font-weight: bold;
}

在 html 文件中添加 ids 如下：

 <div class="modal fade"  style="border-radius : 20px !important;" id="createPageModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalCenterTitle" aria-hidden="true">
                    <div class="modal-dialog modal-dialog-centered"  style="border-radius : 20px !important;" role="document">
                       <!--here--> <div class="modal-content" id="page_modal_content">
                       <!--here--><div class="modal-header" id="page_modal_header">
                                <h5 class="modal-title" id="exampleModalLongTitle">Please enter your credentials to login.</h5>
                                <button type="button" class="close" data-dismiss="modal" aria-label="Close">
                                    <span aria-hidden="true">&times;</span>
                                </button>
                            </div>
                            <div class="modal-body"> 
                                <form class="login_form ">
                                    <label for="user_form_name">User name</label>
                                    <input id="user_form_name" type="text" placeholder="User name" required />
                                </form>
                            </div>
                            <div class="modal-footer">
                                <button style="border-radius : 20px; width : 45%;" type="button" class="btn btn-danger" data-dismiss="modal">Cancel</button>
                                <button style="border-radius : 20px; width : 45%;" type="button" class="btn btn-success">Save changes</button>
                            </div>
                        </div>
                    </div>
                </div>

而 css 应该是：

#page_modal_content {
  border-radius: 10px !important;
} 
#page_modal_header {
  border-top-right-radius: 10px !important;/* you must add important*/
  border-top-left-radius: 10px !important;
}
