CSS scroll-padding-block-end insetting the scrollport at the block-end edge
Definition

Definition and Usage

The scroll-padding-block-end property insets the scrollport at the block-end edge. Snap and scroll targets stop inside that inset instead of flush against the end.

In horizontal writing mode, block-end is usually the bottom. It is the longhand paired with scroll-padding-block-start, and both are set by scroll-padding-block. It is not inherited.

Baseline Widely available.

Not deprecated. Logical longhand for the block-end scrollport inset. Widely available since September 2021 (Safari 15+). Works on any scroll container, with or without snap.

How to Use scroll-padding-block-end

Set it on the scroll container when content should clear the block-end edge.

  1. Create a scroll container (overflow: auto or the document).
  2. Optionally snap with scroll-snap-type and scroll-snap-align: end.
  3. Set scroll-padding-block-end to match a footer height or breathing room.
  4. Scroll — end-aligned targets stop above the inset.

CSS Examples

Each snippet focuses on scroll-padding-block-end. Use Try It Yourself for a live editor.

Example 1 — Length Inset at Block-end

Reserve space at the end edge so snapped panels clear a footer band.

CSS
<style>
  .scroller {
    height: 200px;
    overflow-y: auto;
    scroll-snap-type: y mandatory;
    scroll-padding-block-end: 48px;
  }

  .panel {
    height: 160px;
    scroll-snap-align: end;
  }
</style>

<div class="scroller">
  <div class="panel">1</div>
  <div class="panel">2</div>
  <div class="panel">3</div>
</div>
Try It Yourself

How It Works

  1. Create a scroller. Overflow defines the scrollport.
  2. Snap on the block axis. y mandatory locks vertical panels.
  3. Align to the end. scroll-snap-align: end aims at the block-end edge.
  4. Inset that edge. 48px keeps snapped panels above the bottom band.

Example 2 — Percentage of the Scrollport

Size the end inset relative to the scroller height.

CSS
<style>
  .scroller {
    height: 200px;
    overflow-y: auto;
    scroll-snap-type: y mandatory;
    scroll-padding-block-end: 20%;
  }

  .panel {
    height: 160px;
    scroll-snap-align: end;
  }
</style>

<div class="scroller">
  <div class="panel">1</div>
  <div class="panel">2</div>
  <div class="panel">3</div>
</div>
Try It Yourself

How It Works

  1. Use a percentage. 20% is relative to the scrollport height here.
  2. Scales with the box. Taller scrollers get a larger end inset.
  3. Still logical. In vertical writing modes, the percentage follows the block axis.
  4. Prefer lengths for fixed footers. Match pixel chrome with px or rem.

Example 3 — Auto (Default)

With auto, the browser usually applies no extra end inset.

CSS
<style>
  .scroller {
    height: 200px;
    overflow-y: auto;
    scroll-snap-type: y mandatory;
    scroll-padding-block-end: auto;
  }

  .panel {
    height: 160px;
    scroll-snap-align: end;
  }
</style>

<div class="scroller">
  <div class="panel">1</div>
  <div class="panel">2</div>
  <div class="panel">3</div>
</div>
Try It Yourself

How It Works

  1. Initial value. Omitting the property is the same as auto.
  2. Usually zero. End-aligned panels snap flush to the block-end edge.
  3. UA freedom. A browser may pick a non-zero offset when it helps readability.
  4. Override when needed. Set a length or percentage for predictable footer clearance.

Edge Cases & Pitfalls

End insets are easy to miss if panels snap to the start edge.

align

Use end snap to see the effect

With scroll-snap-align: start, a block-end inset may look unused. Prefer end (or scroll to the last panel) when testing.

logical

Not always the physical bottom

In vertical writing-mode, block-end is a horizontal edge. Prefer this longhand over scroll-padding-bottom when flow can change.

target

Set it on the scroller

Targets use scroll-margin-block-end. The container uses scroll-padding-block-end.

layout

It is not padding-block-end

Layout does not shift. Only scroll and snap aiming change inside the scrollport.

Compatibility

Browser Support

scroll-padding-block-end is a browser CSS property. Node.js, Deno, and Bun do not apply it.

Bottom line: Safe for modern sites. Prefer the logical longhand when writing-mode may change. Not a server runtime API.

Remember

Key Takeaways

  • Role: inset the scrollport at the block-end edge only.
  • Values: auto, length, or percentage.
  • Initial value: auto. Not inherited.
  • Tip: pair with scroll-snap-align: end to see the bottom inset clearly.

One line: scroll-padding-block-end reserves space at the block-end of the scrollport — usually the bottom.

Frequently Asked Questions

It insets the scrollport at the block-end edge. In horizontal writing mode that is usually the bottom, so snap and scroll targets stop above that edge.
The initial value is auto. Browsers usually treat that like 0px unless they choose another offset.
scroll-padding-bottom is always the physical bottom. scroll-padding-block-end follows the block flow, so it adapts when writing-mode is vertical.
scroll-padding-block is the shorthand for both block-start and block-end. This longhand sets only the end side.
Use it for fixed footers, bottom chrome, or extra space when panels snap to the end edge of a scroller.
It is Baseline and widely available since September 2021: Chrome 69+, Edge 79+, Firefox 68+, Safari 15+, Opera 56+. Internet Explorer does not support it. It is a browser CSS property, not a Node.js feature.
