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 Web application 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 Calculator web app from the ground up with just HTML5, CSS and Javascript in less than an hour..

You'll learn:

1. How to create the HTML5 structures of an app. 

2. How to make an app pretty with CSS (design, design, design!) 

and last but never the least 

3. How to make an app work (solve problems) with logic, i.e Javascript 

By the end of the course, you'll be one stop closer to creating web apps like a pro. You could even try creating other smaller web apps. 

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, and what we'll be using to achieve the same results. 

Module 1: 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 2: Here, we'll "beautify" our app. We'll be using CSS elements to give our app colors and styles. At the end of this module, we'll have a calculator app that looks like the final result, albeit one that does not perform any calculations yet. 

Module 3: This would be the meat of the course. We'll be delving into Javascript in this module, and I'll teach you how to make the app work (perform calculations and display the results) in here. 

Final section: Finally, I'll give you some ideas on how to improve the app 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 have the passion for programming, and if you know the basics of at least HTML5 and CSS, this course will take you one step further in your development skills. 

3. If you're a complete newbie, don't worry. I'll be explaining every single line of code I'll be using in this course, so you won't feel lost. 

So, what are you waiting for? Get this course today, and begin your journey into the wonderful world of web development!

Who is the target audience?
  • This course is for people who want to learn web development the fun way

Entrepreneur and programmer with 8 & 10 yrs experience resp.

I've been making money online for over 6 years now, right from when I finished high school. I kept equipping my knowledge and trying out new methods throughout college, so when I finished my studies, I can work for myself and someone else. I'm proud to say that I accomplished that goal.

My businesses involve affiliate marketing, services, list building, Kindle etc. I believe in keeping my eggs in various baskets, and I preach what I practice & believe.

I recently decided to document my methods and knowledge in the form of helpful information products. I believe in being as thorough as possible, and that's what you'll find in my courses.

I cover every aspect of a business or method so my student is equipped with the complete knowledge they need to start their business and run it successfully.
