For this tutorial we're going to make Modal with React Hooks.
1. Create a button
First, let's create a button inside our Modal.js file
{/* Modal.js */}
import React from 'react';
export default function Modal() {
return (
<div>
<button className="btn btn-toggle btn-primary">
Click Me!
</button>
</div>
);
}
/* style.css */
/* base */
@import url('https://fonts.googleapis.com/css2?family=Poppins:wght@300;400;500;600;700&display=swap');
* {
font-family: 'Poppins', sans-serif;
}
body {
padding: 0;
margin: 0;
}
/* button */
.btn {
border: none;
padding: 9px 18px;
border-radius: 8px;
}
.btn-toggle {
font-weight: 600;
position: absolute;
top: 50%;
left: 50%;
transform: translateX(-50%);
}
.btn-primary {
background-color: #0085ff;
color: #ffffff;
}
2. Create Modal
Then, add our modal code just below the button
{/* Modal.js */}
import React from 'react';
export default function Modal() {
return (
<div>
<button className="btn btn-toggle btn-primary">
Click Me!
</button>
<div className="modal-container"></div>
<div className="modal-dialog">
<div className="modal-content">
<div className="modal-header">
<h3>Modal Header</h3>
<button className="modal-close">
<svg
xmlns="http://www.w3.org/2000/svg"
width="25"
height="25"
preserveAspectRatio="xMidYMid meet"
viewBox="0 0 24 24"
>
<path
fill="currentColor"
d="M6.4 19L5 17.6l5.6-5.6L5 6.4L6.4 5l5.6 5.6L17.6 5L19 6.4L13.4 12l5.6 5.6l-1.4 1.4l-5.6-5.6Z"
/>
</svg>
</button>
</div>
<div className="modal-body">
<p>
Lorem ipsum dolor sit amet consectetur adipisicing elit. Vitae
culpa, inventore alias ab atque similique quod ea reprehenderit.
</p>
</div>
<div className="modal-footer">
<button className="btn">
Close
</button>
<button className="btn btn-primary">Okay</button>
</div>
</div>
</div>
</div>
);
}
/* style.css */
/* modal */
.modal-container {
width: 100%;
min-height: 100vh;
position: absolute;
top: 0;
background-color: #0000007d;
}
.modal-dialog {
max-width: 500px;
margin-right: auto;
margin-left: auto;
display: flex;
align-items: center;
min-height: calc(100vh - 2.1rem * 2);
max-height: calc(100vh - 2.1rem * 2);
}
.modal-content {
border: 1px solid #e0dcda;
border-radius: 12px;
background-color: #ffffff;
position: relative;
}
.modal-header {
border-bottom: 1px solid #e0dcda;
padding: 14px 16px;
border-radius: 12px 12px 0 0;
display: flex;
justify-content: space-between;
align-items: center;
}
.modal-header .modal-close {
background: transparent;
border: none;
display: flex;
justify-content: center;
align-items: center;
}
.modal-header h3 {
margin-bottom: 0;
margin-top: 0;
font-size: 16px;
font-weight: 600;
}
.modal-body {
padding: 16px;
overflow-y: auto;
max-height: calc(100vh - 7rem * 2);
}
.modal-footer {
border-top: 1px solid #e0dcda;
padding: 14px 16px;
border-radius: 0 0 12px 12px;
display: flex;
}
.modal-footer .btn:first-child {
margin-right: 8px;
margin-left: auto;
}
3. Add onClick handler
So the logic is when the btn-toggle is clicked, it will set state show to true and then add class show to modal-dialog and when the modal-container or modal-close button is clicked, it will set state show to false and then add class hide to modal-dialog.
{/* Modal.js */}
import React, { useState } from 'react';
export default function Modal() {
const [show, setShow] = useState(false);
const handleShow = () => {
setShow((current) => !current);
};
return (
<div>
<button className="btn btn-toggle btn-primary" onClick={handleShow}>
Default Modal
</button>
<div
className={`modal-container ${show === true ? 'show' : 'hide'}`}
onClick={handleShow}
></div>
<div className={`modal-dialog ${show === true ? 'show' : 'hide'}`}>
<div className="modal-content">
<div className="modal-header">
<h3>Default Modal</h3>
<button className="modal-close" onClick={handleShow}>
<svg
xmlns="http://www.w3.org/2000/svg"
width="25"
height="25"
preserveAspectRatio="xMidYMid meet"
viewBox="0 0 24 24"
>
<path
fill="currentColor"
d="M6.4 19L5 17.6l5.6-5.6L5 6.4L6.4 5l5.6 5.6L17.6 5L19 6.4L13.4 12l5.6 5.6l-1.4 1.4l-5.6-5.6Z"
/>
</svg>
</button>
</div>
<div className="modal-body">
<p>
Lorem ipsum dolor sit amet consectetur adipisicing elit. Vitae
culpa, inventore alias ab atque similique quod ea reprehenderit.
</p>
</div>
<div className="modal-footer">
<button className="btn" onClick={handleShow}>
Close
</button>
<button className="btn btn-primary">Okay</button>
</div>
</div>
</div>
</div>
);
}
/* style.css */
/* important part */
.hide {
display: none;
}
.show {
display: flex;
}
Static Modal
For static modal, simply remove the function handleShow in modal-container
{/* Modal.js */}
{/* ... */}
{/* remove the onClick in modal-container */}
<div className={`modal-container ${show === true ? 'show' : 'hide'}`}></div>
{/* ... */}
Scrollable Modal
You can also make a scrollable modal.
Simply add overflow-y: auto; and max-height to our modal-body in our CSS file.
/* style.css */
.modal-body {
padding: 16px;
overflow-y: auto;
max-height: calc(100vh - 7rem * 2);
}
With Image Inside Modal
Image can also be included inside our modal.
Just don't forget to set our image's width to 100% so it will fit inside our modal-body
{/* Modal.js */}
{/* ... */}
{/* remove the onClick in modal-container */}
<div className="modal-body">
<img
className="modal-img"
src="https://asset.kompas.com/crops/NsA-H96AvvPUMjunfBGSqylkSUI=/0x0:1000x667/750x500/data/photo/2022/07/29/62e36ad288459.jpg"
alt="Dobberman"
/>
<br />
<br />
<p>This is an image of a black dobberman</p>
</div>
{/* ... */}
/* style.css */
.modal-img {
width: 100%;
}
And just like that, you have created your own react hooks modal without any additional library. You can check the repo here.
