Good morning, everyone.
On the mobile phone, I try to center the image of the search results. I can't do it despite all the tests I did in the CSS files (main.css and bootstrap.min)
Someone could tell me what I need to do to center my image.
I attach a photo of the results displayed on PC and a photo of the results displayed on the mobile phone.
Thank you in advance for your help.

Try to use css styles on images:
margin:0 auto; display:block; float:none;
or set parent block to:
width:100%;text-align:center;
and image to:
width:auto;display:inline-block;float:none;

Hello.
Thank you for your answer.
I used the code:

margin:0 auto; display:block; float:none;
but social network images were vertically superimposed
So I assigned your code to the "listing-thumb" in bootstrap.min like this:

.listing-thumb {
    width:100%;text-align:center;
    margin:0 auto; display:block; float:none;
}
It works perfectly.
Thank you very much for your help.
