Thank you for your response.
This code works (with one # missing) and I thank you very much for that:
div#bwg_thumbnails_0 {
margin:auto;
}
But it’s just a patch, I have to duplicate this code by changing the id so that my pages containing multiple galleries are displayed correctly.
It should not be necessary to correct the behaviour of the gallery with CSS code, except to customize something.
For example, I had to put all this CSS code because I have up to 32 galleries on a single page :
div#bwg_thumbnails_0 {
margin:auto;
}
div#bwg_thumbnails_1 {
margin:auto;
}
div#bwg_thumbnails_2 {
margin:auto;
}
div#bwg_thumbnails_3 {
margin:auto;
}
div#bwg_thumbnails_4 {
margin:auto;
}
div#bwg_thumbnails_5 {
margin:auto;
}
div#bwg_thumbnails_6 {
margin:auto;
}
div#bwg_thumbnails_7 {
margin:auto;
}
div#bwg_thumbnails_8 {
margin:auto;
}
div#bwg_thumbnails_9 {
margin:auto;
}
div#bwg_thumbnails_10 {
margin:auto;
}
div#bwg_thumbnails_11 {
margin:auto;
}
div#bwg_thumbnails_12 {
margin:auto;
}
div#bwg_thumbnails_13 {
margin:auto;
}
div#bwg_thumbnails_14 {
margin:auto;
}
div#bwg_thumbnails_15 {
margin:auto;
}
div#bwg_thumbnails_16 {
margin:auto;
}
div#bwg_thumbnails_17 {
margin:auto;
}
div#bwg_thumbnails_18 {
margin:auto;
}
div#bwg_thumbnails_19 {
margin:auto;
}
div#bwg_thumbnails_20 {
margin:auto;
}
div#bwg_thumbnails_21 {
margin:auto;
}
div#bwg_thumbnails_22 {
margin:auto;
}
div#bwg_thumbnails_23 {

div#bwg_thumbnails_24 {

div#bwg_thumbnails_25 {
