Pinterest like button interaction animation using React + Framer motion

Live site

Repo

When I noticed this UI button interaction, I was like

• set up a react project

npx create-react-app

• Add framer-motion

 npm install framer-motion  

Now everything is ready.

This is how we're going to achieve this effect...!

HTML STRUCTURE

Create the main component, and add the button wrapper and button elements.

Now add the main component and styles to our App component.

Add some default styles to our Project

@import url('https://fonts.googleapis.com/css2?family=Inter:wght@400;500&display=swap');


:root {
    --bg: hsla(330, 6%, 12%, 1);
    --button: hsla(160, 27%, 98%, 1);
    --buttonText: hsla(330, 8%, 20%, 1);
    --notSelected: hsla(330, 6%, 46%, 1);




}

html {

    scroll-behavior: smooth;
    text-rendering: optimizeSpeed;
    min-width: 100%;
    overflow-x: hidden;
    font-size: 100%;

}

* {
    margin: 0;
    padding: 0;
    box-sizing: border-box;



}

*::after,
*::before {
    box-sizing: border-box;
}

img {
    max-width: 100%;
    display: block;
    overflow: hidden;
}

a {
    text-decoration: none;
}

svg {
    width: 24px;
    height: 24px;
    pointer-events: none;
}

body {
    background-color: var(--bg);

    font-family: 'Inter',
        sans-serif;
    font-weight: 400;
    line-height: 1.75;
    position: relative;
    transition: background 0.4s ease-in-out;
}

Fun part

Create a Separate component for our animation(span element)

Now import motion from framer motion add it to our span element and add a layoutId button(will explain about this later).

Setting up a state using useState hook

Now add motion to our both buttons and wrap both buttons by Animateshared layout from framer motion.

1. Based on the state, we're going to add a class to our button element active and non-active class.

2. Based on the state, we're going to render the Anicomp.

3. Now add the Onclick event to both buttons and set the button state regarding each button.

Button styles

 button {
            appearance: none;
            border: none;
            background-color: unset;
            font-size: 1rem;
            letter-spacing: 4px;
            padding: 1.125em 1.5em;
            position: relative;
            border-radius: 50px;
            cursor: pointer;
  }


//  active and non active classes
        .active {
            color: var(--buttonText);
        }

        .notActive {
            color: var(--notSelected);
        }

 //span element styles
    .button--bg {
        position: absolute;
        left: 0;
        right: 0;
        top: 0;
        right: 0;
        background: var(--button);
        display: block;
        width: 100%;
        height: 100%;
        z-index: -1;
        border-radius: 50px;
    }

Final Output

AnimateShared Layout

Animateshared layout changes across, and between, multiple components. with help of the same layout id, framer motion shares the transition across the components.
