Welcome to the Q&A Forum

Using CSS/HTML in Dreamweaver CC, I am trying to display a SEO friendly matrix of six images wide by three deep on the Home Page, but cannot get the first (top left) image to display consistently. The page appears correctly in Dreamweaver Design View, but not in the Live View. Equally it works fine in Safari, but not in Firefox nor I.E. I seem to have tried every CSS variation to resolve this issue, without success. Can someone stear me in the right direction, please? The relevant HTML Code ...

We wish to create a minimalist Lightbox (without flashy transitions) for our home page that displays a matrix of 4 x 4 images - sixteen in all. Each image (approximately 240 wide x 360 high) needs to have its own descriptive text and a hyperlink to the appropriate page on our web site. We are trying to identify a simple yet effective SEO friendly add-on that will allow us to quickly change the Lightbox on a daily basis. Suggestions from the Moz community would be very welcome. Thanks

We sell a great number of insulation products, many of which are produced by individual manufacturers. On the page identified below the Keyword "Kingspan" is repeated numerous times as these items are included in our online shop. However, the many mentions of Kingspan are recorded in the HTML5 Source Code, rather than an external database. When I used the MOZ On-Page Grader, using the keywords "Kingspan" I was surprised to achieve an "A" Grade! I know I shouldn't be complaining, but I am wondering why the significant repetition of the word "Kingspan" has not negatively impacted my score? http://www.just-insulation.com/001-eshop/buy-kingspan-thermapitch-thermawall-thermafloor-insulation-boards.html

Does it make sense to use the Canonical statement on pages on your web site that already have the correct URL. Or, should I ask, "Does it do any harm?"
