使用纯CSS创建向上和向下箭头图标或按钮 [英] Create Up and Down arrow icons or buttons using pure CSS
问题描述
我试图使用纯CSS创建下面显示的向上和向下控制按钮,并且没有背景图片。
但是当我在 li.className:在
或 li.className之后:
之前移动主箱子的位置。
以下是我正在收到的问题的小提琴> http ://jsfiddle.net/8usFk/
以下是相同的代码:
HTML
< div class =positionCameras>
< ul>
< li title =上移class =cameraLeftid =cameraUp>< / li>
< li title =Cameraclass =cameraIcon>< / li>
< li title =下移class =cameraRightid =cameraDown>< / li>
< / ul>
< / div>
CSS
.positionCameras ul,.positionCameras li {
margin:0;
padding:0;
list-style:none;
display:inline-block;
}
.positionCameras li.cameraLeft,.positionCameras li.cameraIcon,.positionCameras li.cameraRight {
width:25px;
height:25px;
光标:指针;
背景:#cccccc;
margin:5px;
border-radius:5px;
border:1px solid #aaaaaa;
box-shadow:1px 2px 15px #cccccc;
}
.positionCameras li.cameraLeft:before {
content:;
width:0;
height:0;
border-style:solid;
border-width:0 5px 10px 5px;
border-color:透明透明#007bff透明;
}
.positionCameras li.cameraIcon {
cursor:default;
}
.positionCameras li.cameraRight:before {
width:0;
height:0;
border-style:solid;
border-width:8.7px 5px 0 5px;
border-color:#007bff透明透明透明;
}
让我知道您是否需要其他信息。
请建议。
内嵌块(或任何其他值,但内联),您可以调整它。
然后,- 居中:
text-align:center
在家长身上。 -
vertical-align
它:line-height:20px
(25px -5px这是伪元素高度的一半)并将vertical-align:middle
设置为伪元素:
.positionCameras ul,.positionCameras li {
margin:0;
padding:0;
list-style:none;
display:inline-block;
vertical-align:top; / * UPDATE * /
}
.positionCameras li.cameraLeft,.positionCameras li.cameraIcon,.positionCameras li.cameraRight {
width:25px;
height:25px;
光标:指针;
背景:#cccccc;
margin:5px;
border-radius:5px;
border:1px solid #aaaaaa;
box-shadow:1px 2px 15px #cccccc;
text-align:center; / * UPDATE * /
line-height:20px; / * UPDATE * /
}
.positionCameras li.cameraLeft:before {
内容:;
display:inline-block; / * UPDATE * /
width:0;
height:0;
vertical-align:middle; / * UPDATE * /
border-style:solid;
border-width:0 5px 10px 5px;
border-color:透明透明#007bff透明;
}
.positionCameras li.cameraIcon {
cursor:default;
}
.positionCameras li.cameraRight:before {
width:0;
height:0;
border-style:solid;
border-width:8.7px 5px 0 5px;
border-color:#007bff透明透明透明;
}
I am trying to create below shown "up and down" control buttons using pure CSS and no Background image.
But when I added the CSS for arrows in "li.className:after
or li.className:before
" the position of main boxes moved.
Here is the Fiddle for the issue I am getting > http://jsfiddle.net/8usFk/
Below is the Code for the same:
HTML
<div class="positionCameras">
<ul>
<li title="Move Up" class="cameraLeft" id="cameraUp"></li>
<li title="Camera" class="cameraIcon"></li>
<li title="Move Down" class="cameraRight" id="cameraDown"></li>
</ul>
</div>
CSS
.positionCameras ul, .positionCameras li {
margin: 0;
padding: 0;
list-style: none;
display: inline-block;
}
.positionCameras li.cameraLeft, .positionCameras li.cameraIcon, .positionCameras li.cameraRight {
width: 25px;
height: 25px;
cursor: pointer;
background: #cccccc;
margin: 5px;
border-radius: 5px;
border: 1px solid #aaaaaa;
box-shadow: 1px 2px 15px #cccccc;
}
.positionCameras li.cameraLeft:before {
content:" ";
width: 0;
height: 0;
border-style: solid;
border-width: 0 5px 10px 5px;
border-color: transparent transparent #007bff transparent;
}
.positionCameras li.cameraIcon {
cursor: default;
}
.positionCameras li.cameraRight:before {
width: 0;
height: 0;
border-style: solid;
border-width: 8.7px 5px 0 5px;
border-color: #007bff transparent transparent transparent;
}
Let me know if you need any other information.
Please suggest.
If you set pseudo to display:inline-block
(or any other values but inline.) you can size it.
Then,
- to center it:
text-align:center
on parent. - To
vertical-align
it :line-height:20px
(25px -5px wich is half of the height of pseudo element) and set :vertical-align:middle
to pseudo element:
.positionCameras ul, .positionCameras li {
margin: 0;
padding: 0;
list-style: none;
display: inline-block;
vertical-align:top;/* UPDATE*/
}
.positionCameras li.cameraLeft, .positionCameras li.cameraIcon, .positionCameras li.cameraRight {
width: 25px;
height: 25px;
cursor: pointer;
background: #cccccc;
margin: 5px;
border-radius: 5px;
border: 1px solid #aaaaaa;
box-shadow: 1px 2px 15px #cccccc;
text-align:center;/* UPDATE*/
line-height:20px;/* UPDATE*/
}
.positionCameras li.cameraLeft:before {
content:"";
display:inline-block;/* UPDATE*/
width: 0;
height: 0;
vertical-align:middle;/* UPDATE*/
border-style: solid;
border-width: 0 5px 10px 5px;
border-color: transparent transparent #007bff transparent;
}
.positionCameras li.cameraIcon {
cursor: default;
}
.positionCameras li.cameraRight:before {
width: 0;
height: 0;
border-style: solid;
border-width: 8.7px 5px 0 5px;
border-color: #007bff transparent transparent transparent;
}
