Learn by Recreating

There are so many things that are possible with design and front end development. One of the best ways I’ve found to learn a new skill is to recreate.

What this looks like for me (most of the times) is scrolling through CodePen, finding myself in awe of a Pen, and setting out to make something similar on my own.

Earlier this week, I found this Pen by Made on Mars. Isn’t it gorgeous?! I’m working on upping my animation skills, and having an SVG appear drawn on the page as you scroll down is something I hadn’t thought of. After a few minutes of scrolling up and down I knew this was something I wanted to learn how to do.

The HTML and CSS were straightforward. I used an SVG I made of a bouquet of flowers and made sure I had classes attached to the correct elements. I’ve worked with animating this SVG before, so I had stroke-dashoffset values for all the components. For this Pen, I wanted to keep the CSS simple, so I used the largest stroke-dashoffset value for all of the elements.

I focused mostly on the JS for this Pen. The original Pen by Made on Mars uses jQuery. Since I usually work with vanilla JS at work, I knew I wanted to rewrite the JS accordingly. This is where things got tricky—and where I learned the most! The Pen I used for inspiration didn’t have any comments, so I had to figure the logic on my own. The main things I learned about are clientHeight, innerHeight, scrollHeight, scrollY.

I had a lot of fun making this pen and can’t wait to put the skills I improved to use again.
