Logo too small

domain: purecarpetcare.uk

Hi Benjamin,

you have this css in your site which makes the logo width to 100px.

You could adjust the number or delete the CSS, using customizer option to adjust the logo size instead.

Thanks Ying for the prompt reply.

I also noticed that the menu is on the second line on smartphones (I.e. beneath the logo), which is not a problem but aesthetically it doesn't look great because it's aligned to the left.

How do I centre it on smartphones?

Thanks in advance.

You could give this CSS a try:

.main-navigation.mobile-menu-control-wrapper {
    margin-right: auto;
}

should I add it to the CSS file or edit the line?

This is how you add CSS:

Already done. Thanks.

No problem :)
