如何使字体大小相对于父div? [英] How to make font-size relative to parent div?

问题描述

我希望我的div中的文本与父div保持相同的大小，比例为％.IE.我希望我的文本的 font-size 占父母div宽度的50％.因此，当页面大小更改时，文本在％中始终保持相同大小.

I want text inside my div to remain same size in % percentage ratio to a parent div. I.E. I want my text to have font-size of 50% of parents div width. So when page size is changing, text always remains the same size in %.

这是我在说的:

.counter-holder{
	display: block;
	position: absolute;
	width:90%;
	height:20%;
	top: 70%;
	left: 50%;
	/* bring your own prefixes */
	transform: translate(-50%, -50%);
}


.counter-element-box{
	position:relative;
	vertical-align: text-top;
	border-style: solid;
    border-width: 1px;
    width: 20%;
    height: 100%;
    float:left;
    margin: 6%;
}

.counter-element-text{
	position:absolute; 
	top:50%; 
	width: 50%;
	max-width:50%;
	display: inline-block;
	height:100%;
	margin-left:50%;
	font-size : 80%;overflow: hidden;
}

.counter-element-value{
	position:absolute; 
	top:50%; 
	width: 50%;
	max-width:50%;
	display: inline-block;
	height:100%;
	padding-left:30%;
	font-size : 80%;overflow: hidden;
}

<div class="counter-holder">
	<div class="counter-element-box">
		<div id="years" class="counter-element-value">
			0
		</div>
		<div class="counter-text counter-element-text" >
		    Years
		</div> 
	</div>
	<div class="counter-element-box">
		<div id="missions" class="counter-element-value">
			0  
		</div>
		<div class="counter-text counter-element-text" >
		    Missions
		</div>
	</div> 
	<div class="counter-element-box">	
		  <div id="team" class="counter-element-value">
			   0 
		  </div>
		  <div class="counter-text counter-element-text" >
		    	Team
		  </div>
	</div>		    	
</div>

以全屏方式运行此代码段，然后尝试调整页面大小，并查看文本大小如何变化且不适合div边框.我如何防止它发生，因此它始终留在边界内?

Run this snippet in full screen and try resizing the page and see how text size is changing and not fitting inside the div borders. How can I prevent it from happening, so it always remains inside the borders?

推荐答案

使用 font-size:x％与父级的宽度无关，但是元素通常具有的字体大小

Using font-size: x% is not relative to the width of the parent but the font-size the element would normally have.

因此，如果您元素的父元素设置 font-size:12px ，则元素中的 font-size:50％表示该元素具有 font-size 6px

So if your element's parent sets font-size: 12px then font-size: 50% in element means that element has a font-size of 6px

您要使用的是视口百分比: vw

例如:字体大小:2vw

.counter-holder{
	display: block;
	position: absolute;
	width:90%;
	height:20%;
	top: 70%;
	left: 50%;
	/* bring your own prefixes */
	transform: translate(-50%, -50%);
}


.counter-element-box{
	position:relative;
	vertical-align: text-top;
	border-style: solid;
    border-width: 1px;
    width: 20%;
    height: 100%;
    float:left;
    margin: 6%;
}

.counter-element-text{
	position:absolute; 
	top:50%; 
	display: inline-block;
	margin-left:40%;
	font-size : 2vw;overflow: hidden;
}

.counter-element-value{
	position:absolute; 
	top:50%; 
	width: 50%;
	max-width:50%;
	display: inline-block;
	height:100%;
	padding-left:30%;
	font-size : 2vw;overflow: hidden;
}

<div class="counter-holder">
			
			<div class="counter-element-box">
				<div id="years" class="counter-element-value">
					0
		    	</div>
		    	<div class="counter-text counter-element-text" >
		    		Years
		    	</div> 
	    	</div>
	    	<div class="counter-element-box">
		    	<div id="missions" class="counter-element-value">
					0  
		    	</div>
		    	<div class="counter-text counter-element-text" >
		    		Missions
		    	</div>
	    	</div> 
		    <div class="counter-element-box">	
		    	<div id="team" class="counter-element-value">
					0 
		    	</div>
		    	<div class="counter-text counter-element-text" >
		    		Team
		    	</div>
	    	</div>		    	
</div>
