Creating a website was an arduous and extensive process with a lot of trial and error. I liked being able to make something the way that I wanted it. To be able to think of something and make it come to fruition.
The biggest challenge in learning HTML/CSS is the monotonous nature of it all. Whether it be reading code from a textbook or the trial and error of the process of making a website.
The aspects I enjoyed learning were the customization of it all. The fact that I could change anything to how I wanted it to be.
