Do tags like <em>,<strong>,<i> or css properties like font-size,text-decoration,font-weight have any impact on the way search engines see my site?

有帮助吗?

If you want to build sites from scratch, focus on the newest HTML version. If you want to look at older sites, yes, it's a good idea to learn older HTML tags. There are a lot of older HTML pages that are still up and running.
