How do I increase the logo height?
By default, your website logo height is capped at 50 pixels - it allows you to upload higher resolution version of your logos (for retina devices) without displaying a huge image in your header. You can increase (or decrease) the value by using the following custom CSS code:
header .logo .website-logo { max-height: 80px; }
You can paste the above code either into your child theme's stylesheet, the Theme Options / Appearance / Custom CSS area or Appearance / Customize / Additional CSS area.
