Many pages on Cambridge Online have blue and grey tabs just underneath the page's heading, which link to related sections. The tabs are a convenient way of navigating between websites, text listings, user reviews and offers.
The blue tab indicates which section you are in. By clicking on the grey tabs, you can navigate to the related sections.
In the example above, the current page lists Text Listings in the Financial Services category. You can also click on the grey Websites tab to display Financial Services websites, the grey Reviews tab to display Financial Services reviews or the grey Offers tab to display Financial Services offers.
