Logo blur and pixelated on mobile devices

Hello there guys,
My design website is almost finished but I got a problem on mobile devices. On desktop the header logo looks very cool but on mobile devices it’s pixelated. I already try to edit some files and installed retina 2x plugin but with no success. I’ll appreciate some help with this problem :frowning:
Here is my website: catalingazdac.ro

Lots of thanks!

Hello @catylicious,

Please try to use the following CSS code.

You can add CSS code in DashboardAppearanceCustomizeAdditional CSS (WordPress 4.7 and up). Also you can add CSS code directly to style.css file of your child theme.

a.custom-logo-link img.custom-logo {
    max-width: 100%;

Please feel free to ask any other questions that you might have.

Kind Regards, Roman.
