This is my first ever post to Stack Overflow and I'm not familiar with forum regulations with posting. So please let me know anything that I have done wrong. I have researched this issue in the forums and nothing I've come across gives me a clear answer. I am trying to create a dropdown menu from the "News" element, but I never get any visible result when running the code. I tried to change the .dropdown-content 's display value to block to see if it would make the list visible, but nothing showed. What am I missing? body{ background-image: url("images/seamless-panda-bear-pattern.jpg"); font

What's the purpose of dropdown-toggle class in bootstrap dropdowns?

Dropdown menus work perfectly with or without the dropdown-toggle bootstrap class being applied to <button> element,so why use it in the first place? The dropdown-toggle class adds the outline: 0; on :focus to the button, so when you click on the button it will not have the surrounding blue border of the "active" element.

Bootstrap响应式前端框架笔记七——下拉菜单

Bootstrap响应式前端框架笔记七——下拉菜单 在Bootstrap的Css框架中,下拉菜单属于组件。一个完整的下拉菜单应该有两部分组成,一个触发按钮与一个选项列表。触发按钮dropdown-toggle类来创建,选项列表有drop-menu类来创建,这两部分元素需要包裹在一个dropdown类元素中,才能正确组合,示例代码如下: <p>正常的下拉菜单样式</p> <div class="dropdown"> <button class="btn btn-default dropdown-toggle"> 下拉菜单 <span class="caret"></span> </button> <ul class="dropdown-menu" > <li><a>白羊座</a></li> <li><a>金牛座</a></li> <li><a>摩羯座</a></li> <li><a>狮子座</a></li> </ul> </div> 默认创建的下拉菜单是隐藏的,为了演示方便,可以将ul的display属性重设: <style> ul{ display: block !important; } </style> 效果如下图: 使用dropdown-menu-left或者dropdown-menu-right可以实现对菜单列表的左对齐或者右对齐。 为列表的li元素添加dropdown
