Spacers

Vertical spacing in HTML emails can be tricky, mainly because of inconsistent support for (and rendering of) margin, padding, and <br> tags.

Here's how easy it is to create simple, yet reliable spacers for your emails, using basic HTML and Tailwind CSS utility classes.

Div

This is the simplest spacer you can use in an HTML email.

<div class="leading-64">&zwnj;</div>

How it works:

  1. leading-64 sets the height with line-height: 64px;
  2. We use &zwnj; to add something inside, so the element can take up height reliably in all email clients

We can define a responsive height:

<div class="leading-64 sm:h-32">&zwnj;</div>

Note that this will only work where @media queries are supported.

Row

Use this one directly inside a <table>:

<tr>
  <td class="h-64"></td>
</tr>

Table

The Row spacer, but as a full <table>.

<table class="w-full">
  <tr>
    <td class="h-64"></td>
  </tr>
</table>

Semantic

We can use an <hr> to create a semantic Spacer.

<p>Paragraph about the weather</p>
<hr class="border-0 text-white my-64 min-h-full">
<p>Paragraph about my day at work</p>

How it works:

  • we hide the line by resetting the border
  • we give it the same color as the background of the page, for Outlook
  • we define height with top and bottom margins

The min-h-full class is used to get it working in Apple email clients.
