HI all,

How can I increase logo size to double is height currently?

Also, need to make the header white space bigger top to bottom. How can this be done?
See attached screenshot…

Hello there,

I hope you are doing well today.

You can use the following CSS code to change the logo and header size by going to Appearance > Customize > Additional CSS and pasting it there.

/*Logo size*/
.logo {
    max-height: 90%;
    height: auto;
    width: 230px;

/*Header size*/
.nav-bar {
    height: 70px;
    max-height: 100%;
    line-height: 70px;

Best Regards,
