Introduction
This article covers the following tech skills:
In this lab, we will explore CSS programming concepts by creating a custom radio button with animation on state change. The lab will guide you through the process of using flexbox to create a layout for the radio buttons, resetting the styles on the <input>
element, and using the ::before
element to create the inner circle of the radio button. By the end of the lab, you will have a better understanding of CSS styling and animation techniques.
Custom Radio Button
index.html
and style.css
have already been provided in the VM.
To create a styled radio button with animation on state change, follow these steps:
- Create a
.radio-container
using flexbox to create the appropriate layout for the radio buttons. - Reset the styles on the
<input>
and use it to create the outline and background of the radio button. - Use the
::before
element to create the inner circle of the radio button. - Create an animation effect on state change by using
transform: scale(1)
and a CSS transition.
Here is an example HTML snippet:
<div class="radio-container">
<input class="radio-input" id="apples" type="radio" name="fruit" />
<label class="radio" for="apples">Apples</label>
<input class="radio-input" id="oranges" type="radio" name="fruit" />
<label class="radio" for="oranges">Oranges</label>
</div>
And here is the corresponding CSS:
.radio-container {
display: flex;
align-items: center;
}
.radio-container * {
box-sizing: border-box;
}
.radio-input {
appearance: none;
width: 16px;
height: 16px;
margin: 0;
border: 1px solid #cccfdb;
border-radius: 50%;
display: grid;
align-items: center;
justify-content: center;
transition: all 0.3s ease;
}
.radio-input::before {
content: "";
width: 6px;
height: 6px;
border-radius: 50%;
transform: scale(0);
transition: 0.3s transform ease-in-out;
box-shadow: inset 6px 6px #ffffff;
}
.radio-input:checked {
background: #0077ff;
border-color: #0077ff;
}
.radio-input:checked::before {
transform: scale(1);
}
.radio {
cursor: pointer;
padding: 6px 8px;
margin-right: 6px;
}
