Ok
1) Sorted this, you added custom css which broke the layout. You did this to centre the logo, however this is not an option for the tablet/mobile layout. If you want to customise the theme to achieve this layout, you will be responsible for fixing layout issues that your customisations cause.
2) Add this to your custom css:
.woocommerce div.product .summary p.price, .woocommerce-page div.product .summary p.price {
font-size: 18px;
}
3) You can adjust the size of the rev slider in the rev slider settings
4) Try this custom css:
.mh-tabletland #logo img {
max-height: 100px;
width: auto;
}
5) Add this:
.mh-tabletland nav#main-navigation .menu > li > a, .mh-tabletland .header-4 nav .menu > li > a {
padding: 14px 0;
font-size: 20px;
}
