I decided to do this challenge to practice, improve, and learn new things about HTML, CSS, JavaScript, Web APIs, and between other things. It was a challenge for me because I had to think “out of the box”.

Random things

Here I wanna share with you random things like articles, talks, resources, codbits, pictures, experiences, etc.


Sometimes it is difficult to find the inspiration or good tools, photos, etc, for using when we wanna do something, so I wanna share with you some links that for me are very useful.

If you know more links, please don't hesitate to share it, I'll be really grateful.
