Creating a triangular design using Tailwind CSS: A step-by-step guide

<div class="">
                <div class="w-16 h-16 border-b-30 border-l-30 border-solid border-black">
                    <div class="h-16 w-16 border-t-30 border-r-30 bg-transparent"></div>
                </div>
</div>

Is it possible to create a triangle shape using only TailwindCSS styles, without the need for additional plugins?

Answer №1

For an interesting effect, consider utilizing the transform property:

<link href="https://unpkg.com/tailwindcss@^2/dist/tailwind.min.css" rel="stylesheet">
<div class="w-16 overflow-hidden inline-block">
 <div class=" h-11 w-11 bg-black rotate-45 transform origin-bottom-left"></div>
</div>

<div class="w-16 overflow-hidden inline-block">
 <div class=" h-11 w-11 bg-black -rotate-45 transform origin-top-left"></div>
</div>

<div class="w-11  overflow-hidden inline-block">
 <div class=" h-16  bg-black -rotate-45 transform origin-top-right"></div>
</div>

<div class="w-11  overflow-hidden inline-block">
 <div class=" h-16  bg-black rotate-45 transform origin-top-left"></div>
</div>

<div class="w-11  overflow-hidden inline-block">
 <div class=" h-16  bg-black -rotate-45 transform origin-bottom-right"></div>
</div>

<div class="w-11  overflow-hidden inline-block">
 <div class=" h-16  bg-black rotate-45 transform origin-bottom-left"></div>
</div>

<div class="w-11  overflow-hidden inline-block">
 <div class=" h-16  bg-black -rotate-45 transform origin-top-left"></div>
</div>

<div class="w-11  overflow-hidden inline-block">
 <div class=" h-16  bg-black rotate-45 transform origin-top-right"></div>
</div>

Alternatively, CSS alone can achieve similar results with just two properties. Explore my collection of triangle shapes at

Another option to consider is incorporating borders into your design.

Check out this Tailwind CSS playground

<!-- down -->
<div class="border-solid border-t-black border-t-8 border-x-transparent border-x-8 border-b-0"></div>
<!-- up -->
<div class="border-solid border-b-black border-b-8 border-x-transparent border-x-8 border-t-0"></div>
<!-- left -->
<div class="border-solid border-r-black border-r-8 border-y-transparent border-y-8 border-l-0"></div>
<!-- right -->
<div class="border-solid border-l-black border-l-8 border-y-transparent border-y-8 border-r-0"></div>

Creating triangles using pseudo-elements:

<script src="https://cdn.tailwindcss.com"></script>
<div>small triangle:</div>
<div class="flex gap-x-1">
  <div class="before:content-['▴']"></div>
  <div class="before:content-['▾']"></div>
  <div class="before:content-['◂']"></div>
  <div class="before:content-['▸']"></div>
</div>

Using pseudo-elements for normal triangles:

<script src="https://cdn.tailwindcss.com"></script>

<div>normal triangle:</div>
<div class="flex gap-x-1">
  <div class="before:content-['▲']"></div>
  <div class="before:content-['▼']"></div>
  <div class="before:content-['◀']"></div>
  <div class="before:content-['▶']"></div>
</div>

Creating triangles with borders:

<script src="https://cdn.tailwindcss.com"></script>
<div>triangle by border</div>
<div class="flex gap-x-3">
  <div class="w-0 h-0 border-8 border-solid border-transparent border-b-black"></div>
  <div class="w-0 h-0 border-8 border-solid border-transparent border-t-black"></div>
  <div class="w-0 h-0 border-8 border-solid border-transparent border-r-black"></div>
  <div class="w-0 h-0 border-8 border-solid border-transparent border-l-black"></div>
</div>

Simplified version of creating triangles with borders:

<script src="https://cdn.tailwindcss.com"></script>

<div>triangle by border (simplify)</div>
<style type="text/tailwindcss">
  @layer components { .triangle { @apply w-0 h-0 border-8 border-solid border-transparent } }
</style>
<div class="flex gap-x-3">
  <div class="triangle border-b-black"></div>
  <div class="triangle border-t-black"></div>
  <div class="triangle border-r-black"></div>
  <div class="triangle border-l-black"></div>
</div>

Perhaps you are considering using a triangle for a tooltip, as shown in this example:

https://i.sstatic.net/BNxlB.png

<div class="group relative mt-4 ml-4 inline-block">
  <button type="button" class="rounded-md border border-neutral-600 px-1">...</button>

  <!-- container for triangle and the menu ↓-->
  <div class="invisible absolute left-0 -mt-[2px] flex flex-col group-focus-within:visible group-active:visible">
     <div class="ml-2 -mb-[1px] inline-block overflow-hidden"> <!-- ← triangle container -->
        <!-- triangle ↓ -->
      <div class="h-3 w-3 origin-bottom-left rotate-45 transform border border-neutral-500 bg-neutral-100"></div>
    </div>

    <!-- menu ↓ -->
    <div class="flex min-w-max flex-col rounded-md border border-neutral-500 bg-neutral-100 px-2 py-1">
      <div class="cursor-pointer hover:underline">Do amazing things</div>
      <div class="cursor-pointer hover:underline">Return</div>
    </div>
  </div>
</div>
