I'v some new div in my code with the last version of core

First I had

<div name="info">
   <sib-display-img></sib-display>
   [...]
</div>

Now I have

<sib-set-div  name="info">
    <div data-content="">
        <sib-display-img></sib-display>
        [...]
    </div >
</ sib-set-div >

So it bring some trouble with my css
