I've spotted this small bug, which is not actually one, but improving it would be great. In case there is a successful search of a github profile and a new search is done which is invalid account, the profile image doesn't get updated, instead the previously searched profile's image is displayed.
Hope you understood what I was trying to convey.
I noticed that the website is not responsive at all. I would love to be able and work on this. :)
In tho photo it shows what the website looks on small screens.
