Programming trouble comes mostly from simple things

English

So I spent over 40 hours of work on what is supposed to be a simple bug. Google Maps are not rendering when the size of the map canvas is above 768px. You would think that is a trivial thing right? Wrong!

Web applications are simple. After all it is just HTML, CSS and JavaScript. When I started web development I thought the most challenging part for me would be JavaScript and learning functional programming concepts. In practical real applications though, my worst bugs were CSS based bugs.
