Webpage columns are too small and I can't see the selected options. Modify parameter with Chrome Inspect function?

I found a parameter in the "Styles" section of the Chrome Inspect function. Is there a way to make a simple plug in or something I can run whenever on the page to modify it if found?

@media screen and (min-width: 300px)
.quixote .input-group, .quixote-modal .input-group {
    width: 250px;
