CSS Only Filterable Gallery With Tabs

A CSS-only gallery that combines a filter with tabs.

It allows you to build an elegant gallery filter that uses tabs to filter a group of items by CSS classes. It was written in pure CSS and HTML checkbox elements and works best with lightweight themes.

How to use it:

1. Group the gallery items using CSS classes as follows:

<div class="cards">
  <div class="project js"></div>
  <div class="project html"></div>
  <div class="project react"></div>
  <div class="project vue"></div>
  <div class="project angular"></div>
  <div class="project js"></div>
  <div class="project html"></div>
  <div class="project react"></div>
  <div class="project vue"></div>
  <div class="project angular"></div>
  <div class="project js"></div>
  <div class="project html"></div>
  <div class="project react"></div>
  <div class="project vue"></div>
  <div class="project angular"></div>
  <div class="project js"></div>
  <div class="project html"></div>
  <div class="project react"></div>
  <div class="project vue"></div>
  <div class="project angular"></div>
</div>

2. Create a set of checkboxes for the filter tabs.

<!-- Show All Tab -->
<input
  class="checkbox-all"
  id="all"
  type="radio"
  name="checkbox"
  checked=""
/>
<label for="all">All</label>
<!-- Tabs -->
<input class="checkbox-js" id="js" type="radio" name="checkbox" />
<label for="js">JavaScript</label>
<input class="checkbox-react" id="react" type="radio" name="checkbox" />
<label for="react">React</label>
<input class="checkbox-html" id="html" type="radio" name="checkbox" />
<label for="html">HTML/CSS</label>
<input class="checkbox-vue" id="vue" type="radio" name="checkbox" />
<label for="vue">Vue</label>
<input
  class="checkbox-angular"
  id="angular"
  type="radio"
  name="checkbox"
/>
<label for="angular">Angular</label>

3. Style the gallery items. OPTIONAL.

.cards {
  display: flex;
  flex-wrap: wrap;
  width: 800px;
}
.project {
  border-radius: 4px;
  box-shadow: 6px 7px 28px 0 rgba(16, 16, 16, 0.7);
  -webkit-transition: all 0.2s linear;
  transition: all 0.3s linear;
}
.project.js {
  border: 3px solid #f1c40f;
}
.project.html {
  border: 3px solid #ff932b;
}
.project.react {
  border: 3px solid #64e1fe;
}
.project.vue {
  border: 3px solid #6edbbe;
}
.project.angular {
  border: 3px solid #e75139;
}

4. Convert the checkboxes into filter tabs.

[type="radio"]:checked,
[type="radio"]:not(:checked) {
  position: absolute;
  left: -9999px;
}
[type="radio"]:checked + label,
[type="radio"]:not(:checked) + label {
  position: relative;
  padding-left: 12px;
  padding-right: 12px;
  letter-spacing: 3px;
  cursor: pointer;
  line-height: 30px;
  font-size: 15px;
  text-transform: uppercase;
  font-weight: 500;
  color: #fff;
  margin-right: 10px;
  margin-left: 10px;
  -webkit-transition: all 0.2s ease;
  transition: all 0.2s ease;
}
[type="radio"]:checked + label:after,
[type="radio"]:not(:checked) + label:after {
  content: "";
  border-radius: 2px;
  height: 20px;
  padding: 5px;
  background-color: #e74c3c;
  position: absolute;
  bottom: 0;
  left: 6px;
  top: -4px;
  z-index: -1;
  -webkit-transition: all 0.2s ease;
  transition: all 0.2s ease;
}
[type="radio"]:not(:checked) + label:after {
  opacity: 0;
  width: 0;
}
[type="radio"]:checked + label:after {
  opacity: 1;
  width: calc(100% - 24px);
}
.checkbox-all:checked + label:after,
.checkbox-all:not(:checked) + label:after {
  background-color: hotpink;

}
