Bootstrap 4-card deck with wrapping element
I am working with Angular (v4.3.1) and Bootstrap (v4.0.0-alpha.6). The template contains two subcomponents:
<div class="card-deck">
<comp1></comp1>
<comp2></comp2>
</div>
Both subcomponent templates have a .card
Bootstrap class as their root element class .
<div class="card">
...
</div>
This, after compiling the results in the following HTML
<div class="card-deck">
<comp1 _nghost-c3="">
<div _ngcontent-c3="" class="card">
...
</div>
</comp1>
<comp2 _nghost-c4="">
<div _ngcontent-c4="" class="card">
...
</div>
</comp2>
</div>
The problem is that the style is .card-deck
not being applied properly if there is an element wrapping the elements .card
.
Bootstrap example only, the problem is strictly related to Bootstrap css, not Angular.

Does anyone know how to work with component structure and styles?

Wrappers are causing problems because divs don't have flex css properties while classes .card
useflex:1 0 0;
Option 1 (not very normal): Imagine that the wrappers are cards and they will be styled like a card. I would advise against this. This can cause a number of problems in the long run.
.card-deck > div {
display: flex;
flex: 1 0 0;
flex-direction:column;
}
.card-deck > div:not(:last-child){
margin-right:15px;
}
.card-deck > div:not(:first-child)
{
margin-left:15px;
}

Option 2 (preferred): Apply the class .card
to the wrapper of the angular element . I have not used angular, by going through these docs you can set the class on the host element. Using @ Component.host. Or define some rules using the corner rendering tool . I cannot advise you on the best approach, I am lacking knowledge of angular.
In the end you would like to receive <comp1 _nghost-c3="" class="card">
