How to Add a Border Around a Video Block on Squarespace

Want to add a border around your video in Squarespace, but running into strange gaps or spacing issues? You’re not alone. What seems like a simple task can get surprisingly annoying thanks to a little bit of built-in padding around video blocks.

The good news? I’ve figured out a reliable way to do it using custom CSS, and I’m going to walk you through it step-by-step.

Why Is There a Gap Around Squarespace Video Blocks?

When you use a native video block in Squarespace, there’s some default padding built into the element. So if you try to add a border, it doesn't hug the video tightly -  instead, it floats with a little awkward space between the border and the actual video.

It’s not technically a bug, but it sure looks like one.

Here’s how to fix it and add a clean, professional-looking border around your Squarespace video.

Step-by-Step: Add a Border to a Video Block in Squarespace

This method only works with videos that are uploaded natively to Squarespace (not YouTube or Vimeo embeds).

Step 1: Go to Custom CSS

1. Log into your Squarespace dashboard.

2. Navigate to Design > Custom CSS.

Step 2: Add the CSS Code

Paste the following CSS code into the custom CSS box:

.sqs-native-video {
border: solid 5px #ffd600 !important;
}

Breakdown of the CSS:

• .sqs-native-video targets the video block.

• border: 5px solid #ffd600; creates a 5-pixel solid border (you can use any color or hex code).

• border-radius: 20px; adds a subtle curve to the corners (optional, but looks slick).

You can fully customize this:

• Border size: 1px, 10px, 15px, etc.

• Border color: Use names like red, black, or hex codes like #333, #ff6600, etc.

• Border radius: Add or remove curves.

Sometimes, you may need to adjust additional padding or margins depending on your layout- but for most Squarespace users, the above code does the trick.
