Hello. I'm doing consulting for an online stationery in Brazil. I have a question that does not make sense to me. According to the W3C, for almost every page of the site, HTML does not follow a particular prairie. The error message is as follows: Error: Element img is missing required attribute src. From line 942, column 173; to line 942, column 273 ecotank" ><img class="owl-lazy" data-src="https://www.ohe.com.br/banners/86/ecotank.jpg" alt="Epson ecotank" /></a> But it does not make sense when analyzing the code. Could someone clarify me better if I should worry about this situation? If it is necessary to view the source code, the site in question is https://www.ohe.com.br
The image is <img class="owl-lazy" data-src="https://www.ohe.com.br/banners/86/ecotank.jpg" alt="Epson ecotank" /> HTML: when we'd expect it to be <img class="owl-lazy" src="https://www.ohe.com.br/banners/86/ecotank.jpg" alt="Epson ecotank" /> HTML: I'm assuming that there's some funky jquery running over the top and doing something with the data-src but I'd suggest putting in a src even if it is just to a 1px transperant gif.
