Need feedback on my personal portfolio project... especially whether the media query good or not

I am getting a horizontal scroll bar before the projects rearrange into one column.

Also, the page is breaking when I manually increase the text size. If you don’t know how to do this, using Firefox go to the ‘View->Zoom’ menu and activate ‘Zoom Text Only’. Then while holding down the Ctrl key scroll your middle mouse button to increase the text size.

Good responsive means not only handling changes in the view port width but also changes in the text size.
