私は LightGallery を使用して画像ギャラリーを作成していますが、これまでのところすべて正常に機能していますが、サムネイルのグリッド全体をページの中央に揃えたいと考えています。今は左側にくっついています。使用したコードは次のとおりです。
<div class="demo-gallery">
<ul id="lightgallery" class="list-unstyled row">
<li class="col-xs-6 col-sm-4 col-md-3" data-responsive="img/alba-iulia.jpg 480, img/1.jpg 480, img/3.jpg 800" data-src="img/alba-iulia.jpg" data-sub-html="">
<a href="">
<img class="img-responsive" src="img/alba-iulia.jpg">
</a>
</li>
<li class="col-xs-6 col-sm-4 col-md-3" data-responsive="img/alba-iulia.jpg 480, img/1.jpg 480, img/3.jpg 800" data-src="img/3.jpg" data-sub-html="">
<a href="">
<img class="img-responsive" src="img/3.jpg">
</a>
</li>
<li class="col-xs-6 col-sm-4 col-md-3" data-responsive="img/alba-iulia.jpg 480, img/1.jpg 480, img/3.jpg 800" data-src="img/1.jpg" data-sub-html="">
<a href="">
<img class="img-responsive" src="img/1.jpg">
</a>
</li>
<li class="col-xs-6 col-sm-4 col-md-3" data-responsive="img/alba-iulia.jpg 375, img/1.jpg 480, img/3.jpg 800" data-src="img/alba.jpg" data-sub-html="">
<a href="">
<img class="img-responsive" src="img/alba.jpg">
</a>
</li>
</ul>
</div>

margin-left: auto および margin-right: auto を使用する必要があるという投稿を読みました(ulで使用しましたが、機能していないようです)。助けてくれてありがとう!
