svg logo for WordPress Sparkling theme via Theme Options

I’ve uploaded my logo in svg format in the dimensions recommended at 76x300 however it spans the width of the header. You can see what I’m seeing at Any advice or suggestions would be greatly appreciated.

Different browsers acts differently with .svg images and that’s why you should specific size separately. You can do it by adding this simple css to Appearance >> Theme Options >> Other >> Custom CSS

#logo img {
    width: 300px;
    height: 76px;

Let me know if this helps.

Worked perfectly. Thank you.
