Need some help plz

why there i have to use col-xs- instead of col-md- , its could not work when i put col-md-6 in both image and personal description one “pagetwo”

I’m not exactly sure what the problem is or what you expect, but if you only use col-md-, then there’s nothing to set the size for anything smaller than col-md-. You can use both xs and md, if you want different configurations for each size.

bt col-md did not support in the code.

Paste the code you’ve written and tell us what you want to achieve…
