 This is part 1 of an animation series I’m doing. It is inspired by Lea Verou’s talk called “[The Humble Border-Radius.](https://www.youtube.com/watch?v=JSaMl2OKjfQ)” I looked at her site and she has a good demo of a bunch of different animations [here](http://lea.verou.me/2011/10/animatable-a-css-transitions-gallery/). My goal here is to create a more comprehensive guide to these different animatable properties–mainly for future reference. Animations play a big part in adding interactivity to the web, so why not explore some possible options?

 Animating the location of objects is one of the most common types of animation. It’s interesting to animate this way because you need to keep in mind how each of the element’s interact with each other to constitute a page.

If you haven’t already, you should check out [part 1](https://brandonrozek.com/2015/09/animatable-box-model/) and [part 2](https://brandonrozek.com/2015/05/animatable-border/) of this series. Animations on text can be used to bring attention, to add importance, or to convey a point. As with all animations, however, keep your user in mind and your text readable.

 I’ve been teaching a small class on web development recently, and after my first lecture, I’ve gained a newfound respect for teachers. Teaching didn’t come as naturally to me as I would have imagined. I tried going in prepared: with a few outlines and a few code demos. Instead of letting my preparation go to waste, I decided to share them here with you on my site. It’s a nice break from the Animatable posts, so I hope you enjoy!

 Javascript has multiple ways you can store your data. Each of these different ways is called a data type, and they each carry different “methods” which are helpful commands. Today, I’ll show you the different data types and methods that I use and how they’re useful.

 Ever had a snippet of code that appears multiple times in different places in your program? Whenever you had to change that snippet, you end up playing this game of search and replace. Functions can help. They exist to abstract your code, making it not only easier to change that little snippet, but to read and debug your code as well.

 When a radio wave hits an antenna, the electrical component of the wave induces a difference of potential in the conductor which gives rise to an electric current.

 Short post today. I wanted to clear out some disk space usage on one of my servers and noticed that the systemd logs were taking up a decent bit. Here are two options to clear out old logs.

 There are many times that I need to slightly mess with a color. The easiest way I found to do it is to use one of the many color functions in the program `Sass`. [Sass](https://sass-lang.com/) is a CSS preprocessor, meaning that it has it's own syntax and it compiles down to CSS. I remember using this before CSS variables became a thing and that was one of the main driving points of Sass.

 On current versions of Docker, you can't mount volumes during image construction. This poses an issue for me as I don't want to replicate gigabytes of data already existing on my disk when it won't appear on the final build. Therefore, instead of building an image with a traditional Dockerfile, we're going to use a bash script on a running base image container and export the filesystem to create the image from.
