It’s not enough for a website to be good: it must be good everywhere, for everyone, every time. One way that we at ITX go about ensuring all the pages we build are up to our standards is by employing visual regression testing tools.  

These tools help to detect unwanted changes or defects in the layout, design, or functionality of a webpage. Normally, someone would need to manually load the page they are testing in a variety of display sizes and devices, then check to make sure none of the elements on that page are broken or unusable at certain sizes.
