Create the HTML5 skeleton for a paint app by declaring doctype and root HTML, then building the head and body with canvas and toolbar.
Build the toolbar skeleton inside a container with a unique id, explain block-level behavior, and prepare tool interactions before wiring the canvas drawing area.
Set up the paint toolbar with 10-pixel padding and absolute positioning, keeping it fixed to the top of the page to reliably compute canvas coordinates for drawing.
Style the toolbar by setting a background color with the background-color property, using color names, hex values, or RGB values. Enable overflow: auto to add a scrollbar when tools overflow.
Position the color input inside the toolbar with relative positioning and maintain the toolbar's absolute position, while using float and 20px left and right margins to space tools.
Align and resize reset and save buttons with text-based widths, add right margins, and finalize the toolbar design; plan to expand the canvas to full width and height.
Master JavaScript basic operators and alerts through practical examples: arithmetic, modulo, and compound assignments, and display results using alert messages and string concatenation.
Learn how one-dimensional arrays store multiple values in a single variable, access elements by zero-based indices, and update or extend arrays with strings and booleans.
On app load, set the initial brush color and establish the color input so the brush uses a default stroke color; update the stroke style when the color changes.
Practice makes perfect. Start your journey into becoming a professional front end web developer here!
At DigiFisk, we like making learning fun. Our courses are interactive and fun with a ton of practical elements to it. We've decided to take it a step further with our Front end Web app development practice series.
Once you learn the syntax of a programming language, the next logical step is to start creating software and apps. But that's where most students get stuck. Problem solving isn't as easy as learning a bunch of syntaxes.
But we aim to make it easy for you.
What will you learn in this course?
In this course, you'll learn how to build your own Drawing/paint App from the ground up with just HTML5 canvas, Javascript and CSS in just a couple of hours.
You'll learn:
1. How to create the HTML5 structures of this app.
2. How to make the app pretty with CSS (design, design, design!)
and last but never the least
3. How to make the app work (draw on the canvas) with logic and algorithm, i.e Javascript
4. Basic concepts of Javascript and HTML5 canvas (concepts related to this project).
By the end of the course, you'll be one stop closer to creating front end web apps like a pro. You could even try creating other smaller web apps and games.
How is this course designed?
I've made this course as easy to understand as possible. I've structured it in such a way that each section will handle one of the 3 languages covered here.
Introduction: This is where I'll explain how the app works, it's various features and what we'll be using to achieve the same results.
Module 1: Every professional developer writes algorithms before creating a software or game. We'll be writing the a step by step algorithm for our app, and I'll be explaining what we'll do in every step.
Module 2: I'll be teaching you how to create the bare bones of the app with HTML5. The result will be a page with all the elements we need in our app, devoid any colors or design elements.
Module 3: Here, we'll "beautify" our app. We'll be using CSS elements to give our game colors and styles. At the end of this module, we'll have a Drawing/Paint web app that'll look like the final result, albeit one that dose not draw on the canvas yet.
Module 4: I'll be covering some basic concepts of Javascript in this module. I'll only cover concepts that we'll need for our app's Javascript code though. If you already know the basics, you can skip this module.
Module 5: I'll be covering some basic concepts of HTML5 canvas in this module. I'll only cover concepts that we'll need for our app's Javascript/HTML5 canvas code though. If you already know the basics, you can skip this module.
Module 6: This would be the meat of the course. We'll be delving into Javascript & HTML5 canvas code of our app in this module, and I'll teach you how to make the app work (let the user draw on the drawing canvas and use the various tools in the toolbar) in here.
Final section: Finally, I'll give you some ideas on how to improve/enhance the app further and make it your own in terms of design and functionalities.
This course is for you if:
1. If you like learning by doing rather than hours of boring theoretical lectures.
2. If you're a complete newbie to the world of web development, or just programming in general, and would like to start creating software with the help of a beginner-friendly course. You'll learn the basics of everything used in this project (HTM5, CSS3, Javascript, HTML canvas). I'll be explaining every single line of code I'll be using in this course, so you won't feel lost.
3. If you have the passion for programming, and if you know the basics of HTML5 and CSS, but you're stuck on the practical aspects of it. Turn your theoretical knowledge into practical knowledge with our course.
4. If you want to delve into the exciting world of front end web app development, this course will take you a couple steps further in the right direction.
5. If you're a Javascript web developer who just wants to try out a new project. Our course welcomes coders of every level, from absolute beginners, to pros.
