Problem

[JiBen89]

hello, I'm actually doing a project for my studies, and I needed to add the lastest post on my website, but there is a mistake on the validator. Any chance you can correct it ? Or maybe the mistake come from my part ?
Thank you very much for taking a look at it. It's the first time for me I use gihub, I don't really know if it's the best place for this post. The error is the next one :

"Error: Element div not allowed as child of element span in this context. (Suppressing further errors from this subtree.)
From line 213, column 39; to line 213, column 100
class="">

<div i
Contexts in which element div may be used:
Where flow content is expected.
As a child of a dl element.
Content model for element span:
