A detailed introduction to Bootstrap list groups

In this chapter we will explain list groups. The list component is used to present complex and custom content in the form of a list. The steps to create a basic list group are as follows:

Add class .list-group to the element ff6d136ddc5fdfeffaf53ff6ee95f185.

Add class .list-group-item to 25edfb22a4f469ecb59f1190150159c6.

The following example demonstrates this:

Example

<ul class="list-group">
    <li class="list-group-item">免费域名注册</li>
    <li class="list-group-item">免费 Window 空间托管</li>
    <li class="list-group-item">图像的数量</li>
    <li class="list-group-item">24*7 支持</li>
    <li class="list-group-item">每年更新成本</li></ul>

Basic list group

The basic list group looks like a list item with the list symbol removed and equipped with some specific styles. The basic list group in the Bootstrap framework mainly consists of two parts:

　☑ list-group: list group container, commonly used is the ul element, of course it can also be an ol or div element

　☑ list-group-item: list item, commonly used is the li element, of course it can also be the div element

For the basic list group, there are not many style settings, mainly setting its spacing, borders and rounded corners. Wait

.list-group {
  padding-left: 0;
  margin-bottom: 20px;
}.list-group-item {
  position: relative;
  display: block;
  padding: 10px 15px;
  margin-bottom: -1px;
  background-color: #fff;
  border: 1px solid #ddd;
}.list-group-item:first-child {
  border-top-left-radius: 4px;
  border-top-right-radius: 4px;
}.list-group-item:last-child {
  margin-bottom: 0;
  border-bottom-right-radius: 4px;
  border-bottom-left-radius: 4px;
}

Badge

The list group with badge is actually a combination of the badge component in the Bootstrap framework and the basic list group. an effect. The specific method is very simple. You only need to add the badge component "badge"

in "list-group-item". The principle is very simple, that is, setting a right float for the badge. Of course, if there are two badges in one at the same time, When the list items appear, the distance between them is also set

.list-group-item > .badge {
  float: right;
}.list-group-item > .badge + .badge {
  margin-right: 5px;
}

Link

Use the 3499910bf9dac5ae3c52d5ede7383485 tag instead of the 25edfb22a4f469ecb59f1190150159c6 tag to form a list group that is all links (also note that ## needs to be #ff6d136ddc5fdfeffaf53ff6ee95f185 tags are replaced with dc6dce4a544fdca2df29d5ac0ea9906b tags). There is no need to add a parent element to each element in the list group

a.list-group-item {
  color: #555;
}a.list-group-item .list-group-item-heading {
  color: #333;
}a.list-group-item:hover,
a.list-group-item:focus {
  color: #555;
  text-decoration: none;
  background-color: #f5f5f5;
}

Button

The elements in the list group can also be buttons directly (it also means that the parent element must be

dc6dce4a544fdca2df29d5ac0ea9906b instead of ff6d136ddc5fdfeffaf53ff6ee95f185 ), and there is no need to wrap a separate parent element for each button. Be careful not to use standard .btn classes

Customized content

The Bootstrap box adds two new styles based on the link list group:

☑ list-group-item-heading: used to define the list item header style

　☑ list-group-item-text: used to define the main content of the list item

The biggest role of these two styles is to help developers customize the content of the list item

State setting

The Bootstrap framework provides state effects for combined list items, especially linked list groups. Such as common status and disabled status, etc. The implementation method is similar to the previously introduced components. In the list group, you only need to add the class name to the corresponding list item:

　☑ active: indicates the current state

　☑ disabled: indicates the disabled state

.list-group-item.disabled,
.list-group-item.disabled:hover,
.list-group-item.disabled:focus {
  color: #777;
  background-color: #eee;
}.list-group-item.active,
.list-group-item.active:hover,
.list-group-item.active:focus {
  z-index: 2;
  color: #fff;
  background-color: #428bca;
  border-color: #428bca;
}

Colorful List Group

The list group component is the same as the warning component , Bootstrap provides different background colors and text colors for different states. You can use these class names to define list items with different background colors

　☑ List-group-item-success: Success, background color green

　☑ list-group-item-info：Information, background color is blue

　☑ list-group-item-warning：Warning, background color is yellow

　☑ list -group-item-danger: Error, the background color is red

If you want to add a background color to the list item, you only need to add the corresponding class name

# based on "list-group-item" ##
