Making a website: bootstrap, part 7. Images are different sizes


#1

I think I have done my coding right as it is the same as in the hint but for some reason the pictures are different sizes when in the full screen preview like this:


In the small screen preview, the pictures are perfect, so I'm not sure if I'm doing something wrong or if its supposed to be like this??
thanks

It is definitely not supposed to look like that -- good for you for noticing and asking about it.

The most likely problem is that you have put your columns INSIDE of each other (nested) instead closing each one before you began the next one.
