How to create a tick mark in a custom checkbox? - html

Question

I want to make a custom checkbox with CSS, but not sure how do it.
.custom-checkbox {
border: 3px solid #7e8a94;
float: right;
height: 20px;
width: 20px;
border-radius: 5px;
cursor: pointer;
display: inline-block;
}
.custom-checkbox.hover {
border: 3px solid #43D8B0;
}
.custom-checkbox.active {
border: 3px solid #43D8B0;
}
.custom-checkbox.active.checkmark {}
<input type='checkbox' class='checkbox'>
<div class="custom-checkbox">
<div class="checkmark"></div>
</div>
I added active class to custom-checkbox on checking, but not sure how to create a tick inside a box then?

Answer 1

You have to manually customize your input & add a label in a way using pseudo elements to get the desired effect in the checkbox you want here.
Also, you can use content: '✔'; in your css to provide a tick on click.
I built you a demo to refer to, check the following code:
[type="checkbox"]:not(:checked),
[type="checkbox"]:checked {
position: absolute;
left: -9999px;
}
[type="checkbox"]:not(:checked)+label,
[type="checkbox"]:checked+label {
position: relative;
padding-left: 25px;
cursor: pointer;
}
[type="checkbox"]:not(:checked)+label:before,
[type="checkbox"]:checked+label:before {
content: '';
position: absolute;
left: 0;
top: -5px;
width: 40px;
height: 40px;
background: #fff;
border-radius: 3px;
box-shadow: inset 0 1px 3px rgba(0, 0, 0, .1);
border-radius: 50%;
background-color: #5cf1b3;
outline: none;
}
[type="checkbox"]:not(:checked)+label:after,
[type="checkbox"]:checked+label:after {
content: '✔';
position: absolute;
top: 8px;
left: 10px;
font-size: 24px;
line-height: 0.8;
color: #fff;
transition: all .2s;
}
[type="checkbox"]:not(:checked)+label:after {
opacity: 0;
transform: scale(0);
}
[type="checkbox"]:checked+label:after {
opacity: 1;
transform: scale(1);
}
<p>
<input type="checkbox" id="test1" />
<label for="test1"></label>
</p>

You will need to use :checked pseudo class for it. In the following example it's using a span tag to create the custom checkbox style, and using a pseudo element :before with a special character ✔ inside for the tick.
.custom-checkbox input {
display: none;
}
.custom-checkbox span {
border: 3px solid #7e8a94;
float: right;
height: 20px;
width: 20px;
border-radius: 5px;
cursor: pointer;
display: flex;
justify-content: center;
align-items: center;
}
.custom-checkbox:hover span,
.custom-checkbox input:checked + span {
border: 3px solid #43D8B0;
}
.custom-checkbox input:checked + span:before {
content: "✔";
}
<label class="custom-checkbox">
<input type="checkbox">
<span></span>
</label>

You can check custom checkbox in different-different states below snippet
/* Base for label styling */
[type="checkbox"]:not(:checked),
[type="checkbox"]:checked {
position: absolute;
left: -9999px;
}
[type="checkbox"]:not(:checked) + label,
[type="checkbox"]:checked + label {
position: relative;
padding-left: 1.95em;
cursor: pointer;
}
/* checkbox aspect */
[type="checkbox"]:not(:checked) + label:before,
[type="checkbox"]:checked + label:before {
content: '';
position: absolute;
left: 0; top: 0;
width: 1.25em; height: 1.25em;
border: 2px solid #ccc;
background: #fff;
border-radius: 4px;
box-shadow: inset 0 1px 3px rgba(0,0,0,.1);
}
/* checked mark aspect */
[type="checkbox"]:not(:checked) + label:after,
[type="checkbox"]:checked + label:after {
content: '✔';
position: absolute;
top: .1em; left: .3em;
font-size: 1.3em;
line-height: 0.8;
color: #09ad7e;
transition: all .2s;
}
/* checked mark aspect changes */
[type="checkbox"]:not(:checked) + label:after {
opacity: 0;
transform: scale(0);
}
[type="checkbox"]:checked + label:after {
opacity: 1;
transform: scale(1);
}
/* disabled checkbox */
[type="checkbox"]:disabled:not(:checked) + label:before,
[type="checkbox"]:disabled:checked + label:before {
box-shadow: none;
border-color: #bbb;
background-color: #ddd;
}
[type="checkbox"]:disabled:checked + label:after {
color: #999;
}
[type="checkbox"]:disabled + label {
color: #aaa;
}
/* accessibility */
[type="checkbox"]:checked:focus + label:before,
[type="checkbox"]:not(:checked):focus + label:before {
border: 2px dotted blue;
}
/* hover style just for information */
label:hover:before {
border: 2px solid #4778d9!important;
}
