bootstrap round-circle class elements with border

问题:

I have a bootstrap carousel with multiple items.

My html:

<div class="carousel w-100 " data-ride="carousel" id="recipeCarousel">
   <div class="carousel-inner w-100" role="listbox">
        <div class="carousel-item active">
            <img class="d-block col-sm-12 col-md-4 rounded-circle mystyle"  src="{% static 'core/src/img/staff_member_01.jpg'%}">
            <img class="d-block col-sm-12 col-md-4 rounded-circle mystyle" src="{% static 'core/src/img/staff_member_02.jpg'%}">
            <img class="d-block col-sm-12 col-md-4 rounded-circle mystyle"  src="{% static 'core/src/img/staff_member_03.jpg'%}">
        </div>
        [...]
  </div>
</div>

my css:

.mystyle{
 border:1px solid #d3232e;
}

As you see in the screenshot below, my issue is that I need to give some padding between the images (handled by bootstrap grid system), and that breaks the border layout.

If I use margin and delete padding

.mystyle{
  margin: 0 0.4em;
  padding: 0!important;
  border:1px solid #d3232e;
}

HELP! :-)

Thank you

You should put the images inside col divs, and make them responsive using img-fluid...

<div class="carousel w-100" data-ride="carousel" id="recipeCarousel">
    <div class="carousel-inner text-center w-100" role="listbox">
        <div class="carousel-item d-flex row active">
            <div class="col-sm-12 col-md-4"><img class="rounded-circle img-fluid mystyle" src="//placehold.it/300"></div>
            <div class="col-sm-12 col-md-4"><img class="rounded-circle img-fluid mystyle" src="//placehold.it/300"></div>
            <div class="col-sm-12 col-md-4"><img class="rounded-circle img-fluid mystyle" src="//placehold.it/300"></div>
        </div>
    </div>
</div>

Then there will be no overlap.

Put every image inside a container.

.round-container{
  display:inline-block;
  margin:10px;
}
