is there a css hack for safari only NOT chrome?

Question

im trying to find a css hack for just safari NOT chrome, i know these are both webkit browsers but im having problems with div alignments in chrome and safari, each displays

Answer 1

At the end I use a little JavaScript to achieve it:

if (navigator.vendor.startsWith('Apple'))
    document.documentElement.classList.add('on-apple');

then in my CSS to target Apple browser engine the selector will be:

.on-apple .my-class{
    ...
}
