Row Border Width Won’t Change

Hi, I’ve got an ongoing problem with borders (namely, there isn’t a nice easy way to set the width) that I’ve been trying to solve for a while. I can’t seem to change the border thickness of a row, no matter what I do. I’ve tried adding custom css in the ‘css styles’ section of the ‘edit row’ options, and even tried the alternative workaround of making a class ‘row-round-corner’ and adding the css under ‘custom css’ in my field as discussed here: https://siteorigin.com/thread/using-css-inside-page-builder-widget/

Upon looking at the basic code it seemed that the ‘border-width’ tag wasn’t being used, but there was a ‘border: 1px;’ in the code so I also added that into my css styles to try and effect any change, with no luck. The ‘border: 1px’ seems to still be there (for whatever reason) and override my css. See screenshots for me adding the code to the css styles box and the resulting page source. The full page is at http://www.absolutegoldfitness.com/blog/three-great-healthy-pancake-recipes/ and the blue row is the one I’m experimenting with.

Thanks!
Alex.
