Before I start, sorry for the use of English ; I can only speak French & English.

Jak problém reprodukovat

I was looking for having a center div contening image, with a link and a description.

This is what the prototype of what I tried :

.<>
[* image.png *]:file *** desc

So I would like to have my div and desc, or at least the div

Očekávaný výsledek

<div style="width:346px" class="figure">
<a href="file">
<img src="image.png" alt="" width="336" height="252" /></a>
<p>desc</p>
</div>

Skutečný výsledek

<div style="width:346px; margin:auto" class="figure">
<a href="file">
<img src="image.png" alt="" width="336" height="252" /></a>
<p style="text-align:center">desc</p>
</div>

Thanks !
