Canvas mode: website breakpoint-by-breakpoint reviews

If you have ever dragged three browser windows around your screen just to compare mobile, tablet, and desktop, you will like this. We built Canvas mode to make responsive reviews effortless.

It lets you open a page once and see multiple breakpoints side by side. You can scroll, compare, and leave clear feedback without juggling tabs or asking the team for new screenshots.

What Canvas does

In Huddlekit, Canvas is a dedicated view for responsive QA. You choose the breakpoints you care about and review them in parallel.

Compare layouts across viewports at a glance
Pin comments to specific elements in each viewport
Capture issues with real context on the live page

This is the fastest way to spot layout drift and visual bugs that only show up at certain widths.

Breakpoint-by-breakpoint reviews: the fastest way to catch layout bugs

Debugging responsive issues is slow when you switch tabs or resize a single window. Canvas keeps everything visible so patterns jump out.

Common wins we see:

Sticky headers that overlap content on one viewport but not another
Button text wrapping on tablet while desktop looks fine
Cards that misalign at 1024 when a grid becomes two columns
Spacing that drifts because a CSS variable changes only at one breakpoint

You do not need devtools to verify what changed. Pair Canvas with Inspect mode to check HTML and CSS in place when you want more detail. We wrote more on that here: Inspect CSS without opening devtools.

How teams use Canvas in practice

Here is a quick workflow we recommend:

Open your review link in Huddlekit and switch to Canvas.
Adjust the sizing of four breakpoints you ship against (mobile, tablet, laptop, desktop).
Scroll to key templates like the hero, navbar, feature cards, footer.
Pin issues where you see them. One pin per problem keeps things clear.
Your developer will get a notification with the issue.

You can give clients guest access to review the same Canvas via the project link. No accounts needed. It replaces a single breakpoint workflow with one shared multi canvas view.

Why this beats screenshot only tools

Screenshots help, but they miss state, hover, sticky, and dynamic content.

Canvas runs on the live page so you see real behavior. Combine it with Comment mode for fast pins and Inspect mode for quick checks. You will find more issues in less time and the notes are easier to act on.
