adjusting SVG logo in navigation bar

Can you try clearing your caching plugin?

I'm still seeing the old CSS being added.

It should be:

.main-navigation .inside-navigation .site-logo.navigation-logo img {
    width: 300px;
    height: auto;
}
.main-navigation.mobile-header-navigation .mobile-header-logo img {
    width: 100px;
    height: auto;
}

Perfect! That did it!! Thanks Leo

No problem. Also just to note that the mobile header logo should be an icon ideally - like the M icon you have.

But it's totally up to you. I think it would look cool with just the icon :)

Oh that makes sense. The logo might be too long. Thanks I'll experiment a bit
