They have a background but it's transparent so it's difficult to read the button text due to the site title appearing behind it. And rather than having the white line which indicates which page is currently selected, if the whole tab could change colour that would be cool. Not sure if this is possible?
Also, when you say chain, should it look like this? Sorry i've got very basic knowledge of coding.
<style>
div[data-site-theme="CA9F34482002C3FC235F7F9F2BF4DE0D463B921CAD2BE9B5"] .tab {
background:rgba(0,0,0,0.5);
div[data-menu-level="2"] .tab {
background:#FF00320;
}
<style>
Many thanks,
Pete
