Components: Unable to style encapsulated components

[kbtz]

In the example below I use the list component and try to apply a background color on list items when the item is hovered. However _ngcontent attributes are added to my CSS selectors and some of the elements generated HTML seems to not receive this attribute making impossible to apply any style to it.

Original Style

I've tried different rules just in case...

  md-list-item:hover {
    background:red;
  }

  md-list-item:hover > div{
    background:green;
  }

  md-list-item > div:hover{
    background:blue;
  }

Injected Style

  md-list-item[_ngcontent-pgx-1]:hover {
    background:red;
  }

  md-list-item[_ngcontent-pgx-1]:hover > div[_ngcontent-pgx-1]{
    background:green;
  }

  md-list-item[_ngcontent-pgx-1] > div[_ngcontent-pgx-1]:hover{
    background:blue;
  }

Generated HTML

<md-list _ngcontent-pgx-1="" dense="" role="list">
    <md-list-item _ngcontent-pgx-1="" role="listitem" class="md-2-line">
        <div class="md-list-item">
            <div class="md-list-text">
                {{ ... }}
            </div>
        </div>
    </md-list-item>
</md-list>

I can't find a way to match the generated div.md-list-item from the component style.

We're still working on theming (see #123) and general strategy for component customization. Stay tuned for more info in the future!

You can get at them with either /deep/ or >>> (even though they are deprecated in CSS) angular supports them. see the page on styling on the angular.io site

Now also deprecated in Angular!

But you can still use ::ng-deep
