And the final question: how to analyze your cross browser test results.
If you have a well-coded responsive WordPress theme, then most likely your screenshots will look pretty much the same.
But of course, in some cases, the overall layout and the different website elements may look slightly different from one browser to another.
If this difference is minor and doesn’t impact user experience, aesthetics, or functionality, then you can even ignore it.
But in worse case scenario, the differences will look unpleasant and will affect user experience.
Or even worse, they can prevent your users from using your website as intended.
Usually, the discovered issues are theme- and CSS-related problems and they can be fixed using browser- or device-targeted custom CSS code segments.
