Why does the site completely break in safari?

Question

css

When testing the site on opencart, I ran into a problem, a good half of styles are disabled in safari (the logo flies, styles for fonts, text colors, buttons) breaking the layout, in other browsers everything is displayed perfectly.
What could be the problem, I don't know what to do anymore??

Answer 4

most likely not optimally laid out. for example, the font may be displayed differently (take up more space) and if this is not taken into account, it may break.
