I have been tasked with improving this website (http://www.bdc-construction.co.uk), and one thing I have noticed, is that my Chrome plugin says it's a W3C valid page, yet the W3C validator says there is 90 errors, mainly...
"(http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd) Line 273, Column 28: omitted tag minimization parameter can be omitted only if OMITTAG NO is specified"
I haven't designed this site initially, I also not sure where this error has come from, any ideas guys?
