After placing the page on the server, I always check and look for some errors on the website.
It turns out that the validator: Ready to check - Nu Html Checker? Threw me some errors and I don’t know how to remove them from the Sitely program.
I even thought about direct interference with individual html files, but I thought that Sitely from the wizard level should deal with it. I attach a screenshot to this topic that indicates errors even in the css file code.
The warnings about the <a name=...> code are way too pedantic, it’s an anchor and historically always been like that. Although HTML5 officially deprecated it, all browsers still support it, and in fact for maximum compatibility it’s best to do it that way. That said Sitely also supports the anchors on layout blocks, so you can use those instead.
The heading level you can set in the text HTML tag setting, so you can control it yourself. It is however also overly pedantic and not a problem in practice.
