Checkboxes in web pages – how to make them bigger? - html

Question

The standard checkboxes rendered in most browsers are quite small and don’t increase in size even when a larger font is used. What is the best, browser-independent way to display larger checkboxes?

Answer 1

In case this can help anyone, here's simple CSS as a jumping off point. Turns it into a basic rounded square big enough for thumbs with a toggled background color.
input[type='checkbox'] {
-webkit-appearance:none;
width:30px;
height:30px;
background:white;
border-radius:5px;
border:2px solid #555;
}
input[type='checkbox']:checked {
background: #abd;
}
<input type="checkbox" />

Answer 2

Actually there is a way to make them bigger, checkboxes just like anything else (even an iframe like a facebook button).
Wrap them in a "zoomed" element:
.double {
zoom: 2;
transform: scale(2);
-ms-transform: scale(2);
-webkit-transform: scale(2);
-o-transform: scale(2);
-moz-transform: scale(2);
transform-origin: 0 0;
-ms-transform-origin: 0 0;
-webkit-transform-origin: 0 0;
-o-transform-origin: 0 0;
-moz-transform-origin: 0 0;
}
<div class="double">
<input type="checkbox" name="hello" value="1">
</div>
It might look a little bit "rescaled" but it works.
Of course you can make that div float:left and put your label besides it, float:left too.

Answer 3

Try this CSS
input[type=checkbox] {width:100px; height:100px;}
<input type="checkbox" />

Answer 4

I tried changing the padding and margin and well as the width and height, and then finally found that if you just increase the scale it'll work:
input[type=checkbox] {
transform: scale(1.5);
}

Pure modern 2020 CSS only decision, without blurry scaling or non-handy transforming. And with tick! =)
Works nice in Firefox and Chromium-based browsers.
So, you can rule your checkboxes purely ADAPTIVE, just by setting parent block's font-size and it will grow with text!
input[type='checkbox'] {
-moz-appearance: none;
-webkit-appearance: none;
appearance: none;
vertical-align: middle;
outline: none;
font-size: inherit;
cursor: pointer;
width: 1.0em;
height: 1.0em;
background: white;
border-radius: 0.25em;
border: 0.125em solid #555;
position: relative;
}
input[type='checkbox']:checked {
background: #adf;
}
input[type='checkbox']:checked:after {
content: "✔";
position: absolute;
font-size: 90%;
left: 0.0625em;
top: -0.25em;
}
<label for="check1"><input type="checkbox" id="check1" checked="checked" /> checkbox one</label>
<label for="check2"><input type="checkbox" id="check2" /> another checkbox</label>
<label for="check3" style="font-size:150%"><input type="checkbox" id="check3" checked="checked" /> bigger checkbox </label>

Here's a trick that works in most recent browsers (IE9+) as a CSS only solution that can be improved with javascript to support IE8 and below.
<div>
<input type="checkbox" id="checkboxID" name="checkboxName" value="whatever" />
<label for="checkboxID"> </label>
</div>
Style the label with what you want the checkbox to look like
#checkboxID
{
position: absolute fixed;
margin-right: 2000px;
right: 100%;
}
#checkboxID + label
{
/* unchecked state */
}
#checkboxID:checked + label
{
/* checked state */
}
For javascript, you'll be able to add classes to the label to show the state. Also, it would be wise to use the following function:
$('label[for]').live('click', function(e){
$('#' + $(this).attr('for') ).click();
return false;
});
EDIT to modify #checkboxID styles

Answer 7

I'm writtinga phonegap app, and checkboxes vary in size, look, etc.
So I made my own simple checkbox:
First the HTML code:
<span role="checkbox"/>
Then the CSS:
[role=checkbox]{
background-image: url(../img/checkbox_nc.png);
height: 15px;
width: 15px;
display: inline-block;
margin: 0 5px 0 5px;
cursor: pointer;
}
.checked[role=checkbox]{
background-image: url(../img/checkbox_c.png);
}
To toggle checkbox state, I used JQuery:
CLICKEVENT='touchend';
function createCheckboxes()
{
$('[role=checkbox]').bind(CLICKEVENT,function()
{
$(this).toggleClass('checked');
});
}
But It can easily be done without it...
Hope it can help!
