+First, let's find a repository (or **repo**) on GitHub of interest to you and to which you'd like to contribute a change. You will want to copy its contents to your machine.
 
 ✅ A good way to find 'beginner-friendly' repos is to [search by the tag 'good-first-issue'](https://github.blog/2020-01-22-browse-good-first-issues-to-start-contributing-to-open-source/).

+We are also using `rem` for the border-radius, a font-relative length. Read more about this type of relative measurement in the [CSS spec](https://www.w3.org/TR/css-values-3/#font-relative-lengths).
 
 ✅ Try changing the jar colors and opacity vs. those of the dirt. What happens? Why?

Perhatikan juga peratusan lebar dan tinggi untuk elemen balang dan bagaimana setiap elemen benar-benar diposisikan di tengah, disematkan ke bahagian bawah pandang.

+# My Terrarium: A project to learn about HTML, CSS, and DOM manipulation using JavaScript 🌵🌱
+
+A small drag and drop code-meditation. With a little HTML, JS and CSS, you can build a web interface, style it, and add an interaction.
+
+![my terrarium](../images/screenshot_gray.png)
+
+## Credits
+
+Written with ♥️  by [Jen Looper](https://www.twitter.com/jenlooper)
+
+The terrarium created via CSS was inspired by Jakub Mandra's glass jar [codepen](https://codepen.io/Rotarepmi/pen/rjpNZY).
+
+The artwork was hand drawn by [Jen Looper](http://jenlooper.com) using Procreate.
+
+## Deploy your Terrarium
+
+You can deploy, or publish your terrarium to the web using Azure Static Web Apps. 
+
+1. Fork this repo
+
+2. Press this button
+
+[![Deploy to Azure button](https://aka.ms/deploytoazurebutton)](https://portal.azure.com/?feature.customportal=false&WT.mc_id=academic-13441-cxa#create/Microsoft.StaticApp)
+
+3. Walk through the wizard creating your app. Make sure you set the app root to either be `/solution` or the root of your codebase. There's no API in this app, so don't worry about adding that. A .github folder will be created in your forked repo that will help Azure Static Web Apps' build service build and publish your app to a new URL.
