如何增加虚线边框点之间的间距 [英] How to increase space between dotted border dots
本文介绍了如何增加虚线边框点之间的间距的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我在我的盒子中使用虚线样式边框
I am using dotted style border in my box like
.box {
width: 300px;
height: 200px;
border: dotted 1px #f00;
float: left;
}
我想增加边框每个点之间的距离。 p>
I want to the increase the space between each dot of the border.
推荐答案
此技巧适用于水平和垂直边框:
This trick works for both horizontal and vertical borders:
/*Horizontal*/
background-image: linear-gradient(to right, black 33%, rgba(255,255,255,0) 0%);
background-position: bottom;
background-size: 3px 1px;
background-repeat: repeat-x;
/*Vertical*/
background-image: linear-gradient(black 33%, rgba(255,255,255,0) 0%);
background-position: right;
background-size: 1px 3px;
background-repeat: repeat-y;
您可以使用背景大小和线性梯度百分比来调整大小。在这个例子中,我有一个1px点和2px间距的虚线。
这种方式你也可以使用多个背景的多个虚线边框。
You can adjust the size with background-size and the proportion with the linear-gradient percentages. In this example I have a dotted line of 1px dots and 2px spacing. This way you can have multiple dotted borders too using multiple backgrounds.
Try it in this JSFiddle or take a look at the code snippet example:
div {
padding: 10px 50px;
}
.dotted {
border-top: 1px #333 dotted;
}
.dotted-gradient {
background-image: linear-gradient(to right, #333 40%, rgba(255, 255, 255, 0) 20%);
background-position: top;
background-size: 3px 1px;
background-repeat: repeat-x;
}
.dotted-spaced {
background-image: linear-gradient(to right, #333 10%, rgba(255, 255, 255, 0) 0%);
background-position: top;
background-size: 10px 1px;
background-repeat: repeat-x;
}
.left {
float: left;
padding: 40px 10px;
background-color: #F0F0DA;
}
.left.dotted {
border-left: 1px #333 dotted;
border-top: none;
}
.left.dotted-gradient {
background-image: linear-gradient(to bottom, #333 40%, rgba(255, 255, 255, 0) 20%);
background-position: left;
background-size: 1px 3px;
background-repeat: repeat-y;
}
.left.dotted-spaced {
background-image: linear-gradient(to bottom, #333 10%, rgba(255, 255, 255, 0) 0%);
background-position: left;
background-size: 1px 10px;
background-repeat: repeat-y;
}
<div>no
<br>border</div>
<div class='dotted'>dotted
<br>border</div>
<div class='dotted-gradient'>dotted
<br>with gradient</div>
<div class='dotted-spaced'>dotted
<br>spaced</div>
<div class='left'>no
<br>border</div>
<div class='dotted left'>dotted
<br>border</div>
<div class='dotted-gradient left'>dotted
<br>with gradient</div>
<div class='dotted-spaced left'>dotted
<br>spaced</div>
