Why does the "container" class in Bootstrap leave side spaces on the page? Is this normal or am I forgetting something?
I need to know how to change the height of each row , as I tried to use height and it does not recognize.
Yes, it is normal. In fact, this is in the documentation .
If you want to take advantage of the side space, you can use the container-fluid
class.
See an example. Note: Unfortunately it does not work right at the original size, click " All Page " to test.
