Spur's FAQ

A little app from ZURB that helps you critique your web designs, giving you that kick you need to make them better.


Classic design principles still prove true today, but there are no good tools out there to help you apply them on the web.

Spur helps you apply those principles to your design and share what you’ve learned with others.

What is Spur?

Spur is a fun and easy way to critique web designs in ways you’ve never done before. Just paste a URL (or upload an image) and you’ll be able to use seven different tools to help you find what’s working (and what isn’t!).

Great! What now?

Share what you’ve learned, of course! Spur generates a unique URL you can use to share your design with any of the tools applied to it. Get feedback from your team by uploading the altered image to Notable; they’ll be more than happy to dig their Spurs into your design.

Why would I do that?

Looking at your web design through Spur’s seven tools will give you new perspective to see things you might have missed. You might think twice about that bright green Buddha after you look at in high contrast! Or maybe not...

How do I use it?

Just type in a URL and press Enter. If your design isn’t live yet, use our image uploader to add a mockup to Spur. You can share your altered image using a unique URL or upload it directly to Notable as a new post.

Not sure where to start? Here are some tips about how to use the seven tools:


What are you left with when the color is taken out of your design? Do the areas of focus still hold up, or does contrast between elements? Make sure your original hierarchical decisions still hold up when you take out the color. Learn how →


Take a look at where the major lines of the page force the eye to focus. Draw your grid lines to show these focal points. A good design will ensure the spurs are on a spot where people can read the maximum amount of information in the minimum amount of time, typically seconds. Learn how →


Every design has intentional areas of focus, but are these areas too overpowering? Bumping up the contrast of a design can help show what areas are really jumping off the page when someone initially views the page. Learn how →


What does your design look like at a glance, without details? Make sure you have solid hierarchy and weight, and that if someone glances for a few seconds they get something valuable. Learn how →


Get a sense of how your page feels without readable copy. Areas you might not expect can jump out at you, and misalignments become more obvious. Learn how →


In an age of different devices and screens, it's valuable to see how your page holds up on its side, or upside down. Could someone get a sense of your site if they saw it on someone's iPad? Learn how →

50% Zoom

Take a look at your site as a smaller thumbnail; does the layout hold up? The best websites still get the story across at a small size. Elements should look balanced and people should still be able to get the gist of what they're seeing. You want them to click through don't you? Learn how →
