Border radius circle
You need a predefined width and height on the span to be able to make it round.
span p {
margin: 0;
}
span {
background-color: red;
display: inline-block;
border-radius: 50%;
width:40px;
height:40px;
padding-left:10px;
box-sizing: border-box;
}<span>
<p>25</p>
<p>08</p>
</span>You can do this by giving the span a fixed width and height:
span p {
margin: 0;
}
span {
background-color: red;
display: inline-block;
border-radius: 50%;
width: 50px;
height: 50px;
text-align: center;
}<span>
<p>25</p>
<p>08</p>
</span>add line-height and width:
span {
background-color: #F00;
display: inline-block;
border-radius: 50%;
width: 50px;
line-height: 25px;
text-align: center;
}
