Using HTML and CSS to create a custom checkbox
Checkboxes are an essential part of any web form that allows users to make a selection. While most web developers use the default checkboxes that come with the browser, there are situations where you may want to create custom checkboxes that fit your website's design.
In this tutorial, we will learn how to create custom checkboxes using HTML and CSS.
HTML
We will start by creating a basic HTML structure for our custom checkbox. First, we will create a label
element that will wrap around our checkbox.
<label class="checkbox">
<input type="checkbox">
<span class="checkmark"></span>
</label>
Inside the label
element, we will add an input
element with a type
attribute of checkbox
. This is the actual checkbox that users will interact with.
Next, we will add a span
element with a class of checkmark
. This is where we will create the custom appearance of our checkbox.
CSS
Now that we have our basic HTML structure, we can add CSS styles to create our custom checkbox.
First, we will style the checkbox
class to give it some basic appearance.
.checkbox {
display: inline-block;
position: relative;
cursor: pointer;
font-size: 16px;
line-height: 1;
padding-left: 25px;
margin-bottom: 15px;
}
Here, we set the display
property to inline-block
so that the checkbox appears on the same line as the label text. We also set the position
property to relative
so that we can position the checkmark within the label.
Next, we set the cursor
property to pointer
to indicate to users that the checkbox is clickable. We also set the font-size
and line-height
properties to ensure that the label text and checkbox are vertically centered.
Finally, we set the padding-left
property to create some space between the checkbox and the label text. We also set the margin-bottom
property to create some vertical space between multiple checkboxes in a form.
Next, we will create the appearance of the checkmark
.
.checkmark {
position: absolute;
top: 0;
left: 0;
height: 20px;
width: 20px;
background-color: #fff;
border: 2px solid #ccc;
border-radius: 4px;
}
input[type="checkbox"]:checked + .checkmark:after {
content: "";
display: block;
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
height: 10px;
width: 10px;
background-color: #ccc;
border-radius: 2px;
}
Here, we set the position
property of the checkmark
to absolute
so that we can position it within the label
element. We also set the top
and left
properties to 0
to position the checkmark in the top-left corner of the label
.
We set the height
and width
properties of the checkmark
to 20px
to create a square shape. We also set the background-color
and border
properties to create a white square with a grey border.
Next, we use the :after
pseudo-element to create the appearance of the checkmark when the checkbox is checked. We use the content
property to add an empty content to the pseudo-element. We set the display
property to block
to make the pseudo-element visible. We also set the position
property to absolute
to position the pseudo-element within the label
element.
We use the top
and left
properties along with the transform
property to center the checkmark within the checkmark
element.
We set the height
and width
properties of the checkmark to 10px
to create a smaller square shape than the checkmark
element. We also set the background-color
and border-radius
properties to create a grey square with rounded corners.
Finally, we use the input[type="checkbox"]:checked + .checkmark:after
selector to target the pseudo-element only when the checkbox is checked. We use the +
selector to select the next sibling element of the input
element, which is the checkmark
element.
