Elastic SVG Sidebar Using Material Design

This code creates an elastic sidebar using Material Design. It uses SVG animations and transitions to reveal and hide content smoothly. Clicking contacts triggers animations to open a chat interface. The sidebar slides in and out with a click.

How to Create Elastic SVG Sidebar Using Material Design

1. First of all, load the Google Fonts by adding the following CDN links into the head tag of your HTML document.

<link rel='stylesheet' href='https://fonts.googleapis.com/css?family=Open+Sans'>

2. After that, create the basic HTML structure for your sidebar interface. Define the necessary elements, including the sidebar container, contacts, chat interface, and any other content areas.

<div class="demo">
  <svg class="sidebar" viewBox="0 0 300 500">
    <path class="s-path" fill="#fff" d="M0,0 50,0 a0,250 0 1,1 0,500 L0,500" />
  </svg>
  <div class="static">
    <div class="static__text">Pull white sidebar to the right</div>
  </div>
  <div class="sidebar-content">
    <div class="contact">

3. Now, add the following CSS code between <style> tag or external CSS file to style the sidebar. This includes defining the layout, colors, fonts, and positioning for various components. Customize the CSS style according to your webiste/app’s theme.

4. Load the jQuery by adding the following script just before closing the body tag:

<script src='//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js'></script>

5. Finally, Implement the JavaScript code provided. This code handles the sidebar animations, interactions with contacts, and the chat interface. It’s responsible for the smooth transitions, sidebar opening/closing, and chat display functionality.

$(document).ready(function() {
  var $svg = $(".sidebar"),

That’s all! hopefully, you have successfully created an Elastic SVG Sidebar using Material Design. If you have any questions or suggestions, feel free to comment below.

Asif Mughal

I code and create web elements for amazing people around the world. I like work with new people. New people new Experiences.
I truly enjoy what I’m doing, which makes me more passionate about web development and coding. I am always ready to do challenging tasks whether it is about creating a custom CMS from scratch or customizing an existing system.
