css使响应椭圆块 [英] css make responsive oval block

问题描述

我想为下面的图片中显示的数字做一个css块。我的想法/目标是使一个响应块，如果有一个数字，它将是圆的，如果两个，然后喜欢第二。我已经尝试使边界半径：50％所以第一块我成功做第二个不像在边框半径的图像：50％

所以我的问题是有可能使用一个类块或每个按钮（左|右）作出这样的结果我需要为每个块写特殊类？

解决方案

固定高度解决方案

为此，你需要一个固定的高度（否则，你需要用jquery计算）。

您需要做的是这样的事情;

  html，body {background：＃222; } div {margin：10px; display：inline-block; height：30px; border-radius：25px;背景：lightblue; font-size：30px; min-width：30px; text-align：center; line-height：30px; padding：10px;位置：相对; color：blue;} div：before {content：; position：absolute; left：0; top：-10px; width：100％; border-top：3px solid tomato; }  

 < div> 1< / div> div> 123< / div>  

注意：border-radius应该设置为这个的总高度的一半。

我还包括一个最小宽度，以确保它总是至少一个圆。

---

JQuery解决方案对于非固定高度

  $ （document）.ready（function（）{$（'div'）。each（function（index）{var height = $（this）.height（）; $（this）.css（border-radius，height +px）;}）;}）;  

  html，body {background：＃222;} div {margin：10px; display：inline-block; border-radius：25px; background：lightblue; font-size：30px; min-width：30px; text-align：center; line-height：30px; padding：10px;位置：相对; vertical-align：top; color：blue;} div：before {content：; position：absolute; left：0; top：-10px; width：100％; border-top：3px solid tomato;}  

 < script src =https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js>< / script>< div> 1< / div>< div> 123< ; / div>< div>不是设置的高度，< br />任一：）< / div>   
I am trying to make a css blocks for numbers shown in image below. My idea / goal is to make one responsive block so if there will be one number it will be round, if two then like second. I have been tried to make border-radius: 50% so the first block I succeed to do second was not like in image with border-radius: 50%

So my question is it possible to make such result with one class block or for each button (left | right) I need to write special class for each block ?

解决方案
Fixed Height Solution

For this you will need a "fixed" height (otherwise, you'll need to calculate this with jquery).

What you'll need to do is something like this;



html,body{background:#222;}
div {
  margin:10px;
  display: inline-block;
  height: 30px;
  border-radius: 25px;
  background: lightblue;
  font-size: 30px;
  min-width: 30px;
  text-align: center;
  line-height: 30px;
  padding: 10px;
  position:relative;
  color:blue;
}
div:before{
  content:"";
  position:absolute;
  left:0;
  top:-10px;
  width:100%;
  border-top:3px solid tomato;
  }

<div>1</div>
<div>123</div>





Note: The border-radius should be set to half the overall height for this.

I've also included a min-width to ensure it is always at least a circle.



JQuery Solution For non-fixed heights



$(document).ready(function() {
  $('div').each(function(index) {
    var height = $(this).height();
    $(this).css("border-radius", height + "px");
  });
});

html,
body {
  background: #222;
}
div {
  margin: 10px;
  display: inline-block;
  border-radius: 25px;
  background: lightblue;
  font-size: 30px;
  min-width: 30px;
  text-align: center;
  line-height: 30px;
  padding: 10px;
  position: relative;
  vertical-align:top;
  color: blue;
}
div:before {
  content: "";
  position: absolute;
  left: 0;
  top: -10px;
  width: 100%;
  border-top: 3px solid tomato;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div>1</div>
<div>123</div>

<div>Not a set height,
  <br/>either :)</div>
