I have looked at the different questions regarding this issue, but couldn't find anything that works due to limitations in my markup.
My markup looks like so (unfortunately as this is generated by some backend, I am unable to change the markup).
<ul>
<li>
<input type="checkbox" value="1" name="test[]" id="myid1">
<label for="myid1">label1</label>
</li>
<li>
<input type="checkbox" value="2" name="test[]" id="myid2">
<label for="myid2">label1</label>
</li>
</ul>
I need the checkbox to be on the right and centered vertically in the <li>
Currently, this is styled as:
li input{
display: inline-block;
float: right;
margin-right: 10px;
}
I have tried using various values for vertical-align, but that doesn't seem to help. Also, in some cases the label can be very long and span multiple lines. The checkbox would still need to be able to vertically center itself when the height of the li is arbitrary.
How can I go about achieving this?
Vertical alignment only works on inline elements. If you float it, then I don't think it is treated as part of that stream of inline elements any more.
Make the label an inline-block, and use vertical alignment on both the label and the input to align their middles. Then, assuming it is okay to have a specific width on the labels and checkboxes, use relative positioning instead of floating to swap them (jsFiddle demo):
input {
width: 20px;
position: relative;
left: 200px;
vertical-align: middle;
}
label {
width: 200px;
position: relative;
left: -20px;
display: inline-block;
vertical-align: middle;
}
Its not a perfect solution, but a good workaround.
You need to assign your elements to behave as table with display: table-cell
Solution: Demo
HTML:
<ul>
<li>
<div><input type="checkbox" value="1" name="test[]" id="myid1"></div>
<div><label for="myid1">label1</label></div>
</li>
<li>
<div><input type="checkbox" value="2" name="test[]" id="myid2"></div>
<div><label for="myid2">label2</label></div>
</li>
</ul>
CSS:
li div { display: table-cell; vertical-align: middle; }
<div>
<input type="checkbox">
<img src="/image.png" />
</div>
input[type="checkbox"]
{
margin-top: -50%;
vertical-align: middle;
}
This works reliably for me. Cell borders and height added for effect and clarity:
<table>
<tr>
<td style="text-align:right; border: thin solid; height:50px">Some label:</td>
<td style="border: thin solid;">
<input type="checkbox" checked="checked" id="chk1" style="cursor:pointer; "><label for="chk1" style="margin-top:auto; margin-left:5px; margin-bottom:auto; cursor:pointer;">Check Me</label>
</td>
</tr>
</table>Add CSS:
li {
display: table-row;
}
li div {
display: table-cell;
vertical-align: middle;
}
.check{
width:20px;
}
ul{
list-style: none;
}
<ul>
<li>
<div><label for="myid1">Subject1</label></div>
<div class="check"><input type="checkbox" value="1"name="subject" class="subject-list" id="myid1"></div>
</li>
<li>
<div><label for="myid2">Subject2</label></div>
<div class="check" ><input type="checkbox" value="2" class="subject-list" name="subjct" id="myid2"></div>
</li>
</ul>The most effective solution that I found is to define the parent element with display:flex and align-items:center
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<style>
.myclass{
display:flex;
align-items:center;
background-color:grey;
color:#fff;
height:50px;
}
</style>
</head>
<body>
<div class="myclass">
<input type="checkbox">
<label>do you love Ananas?
</label>
</div>
</body>
</html>
OUTPUT:
make input to block and float, Adjust margin top value.
HTML:
<div class="label">
<input type="checkbox" name="test" /> luke..
</div>
CSS:
/*
change margin-top, if your line-height is different.
*/
input[type=checkbox]{
height:18px;
width:18px;
padding:0;
margin-top:5px;
display:block;
float:left;
}
.label{
border:1px solid red;
}
