Issue with text boxes moving when site re-sized

Issue with text boxes moving when site re-sized

All
This question is in relation to my website www.elitedentalstaffing.com
Can anyone tell me why the two text boxes above "Learn More" and "Join Our
Team" move when I zoom in, in my browser. I am using Chrome but have seen
the same thing in IE. The strange thing is the text box above "Request
Staffing Support" does not move when I zoom in and is basically the same
as the other two text boxes. I am new to coding so am just not sure what I
am doing wrong. Hoping for a simple fix. Worst case scenario I can burn
the text into the image but do not want to do that if possible.
Thanks
