nth-child being ignored by the browser in bootstrap panels

I have <%= render @inspirations %>, which renders 4 inspirations:

enter image description here

VIEW CODE

<div class="panel panel-default">
  <div class="panel-body">
    <%= link_to inspiration_path(inspiration) do %>
      <%= inspiration.name %>
    <% end %>
  </div>
</div>

But I want to remove the border:white on the left side for odd number and on the right side for even number inspirations (this way the panels touch the edges of the screen).

What I have right now for nth-child is being ignored by the browser

CODE

.home-panels a:nth-child(odd) .panel-default {
  border-left: 0px !important;
}
.home-panels a:nth-child(even) .panel-default {
  border-right: 0px !important;
}
.home-panels {} .panel-default {
  border: 2.5px white solid;
}
.panel-body {}
<div class="home-panels">
  <div class="panel panel-default">
    <div class="panel-body">
      <a href="/inspirations/37-testing-to-see-border">
        <div class="white-link">Testing to See Border</div>
      </a>
    </div>
  </div>
  <div class="panel panel-default">
    <div class="panel-body">
      <a href="/inspirations/36-testing-words">
        <div class="white-link">Testing Words</div>
      </a>
    </div>
  </div>
  <div class="panel panel-default">

Solution

  • You are applying the nth-child to wrong selector, here's your current selector:

    .home-panels a:nth-child(odd) .panel-default

    You are saying the a would be child of .home-panels (which is OK, altought is in fact a grand-child), but parent of .panel-default(so not OK), which means this rule would never work given your current HTML markup.

    So, instead of the a has to be the div with class panel panel-default, which is the parent of the a and which as siblings panel panel-default.

    .panel-default:nth-child(odd) {
  border-left: 0px
}
.panel-default:nth-child(even) {
  border-right: 0px 
}
.panel-default {
  background: url("//dummyimage.com/200x200");
  border: 3px red solid;
  height:200px;
  width:200px;
  display:inline-block;
  margin:2px
}
    <div class="home-panels">
  <div class="panel panel-default">
    <div class="panel-body">
      <a href="/inspirations/37-testing-to-see-border">
        <div class="white-link">Testing to See Border</div>
      </a>
    </div>
  </div>
  <div class="panel panel-default">
    <div class="panel-body">
      <a href="/inspirations/36-testing-words">
        <div class="white-link">Testing Words</div>
      </a>
    </div>
