The web should be accessible for everyone. This often isn’t the case for people who are blind, visually impaired, deaf, hard of hearing, mobility impaired, or have reading difficulties, to name a few. 

About 15% of the world’s population has a disability — that’s more than 1 billion people who have a negative user experience when designs don’t consider accessibility.

Inaccessibility on the web isn’t caused by disabilities or a lack of tools, but by designs that interfere with assistive technology (AT). AT includes settings and devices that help people interact with the digital world. 

Examples of AT include: 

  • Screen readers: read text and page elements aloud for people who are blind and low vision
  • Magnification: increase the size of objects on the screen for people with low vision 
  • Keyboards: use keyboard commands (instead of a mouse) for people with limited mobility
  • Voice dictation: use speech (instead of a mouse and keyboard) for people with more severe mobility impairments 

Pave the way for equity on the web with good design + assistive technology

Webflow has committed to building a better, more accessible web, and this effort relies on us working together as a community to be mindful of best practices, primarily those of the Web Content Accessibility Guidelines (WCAG)

WebAIM analyzed a million homepages and found 98% had preventable accessibility barriers. We recently made updates to make top components more accessible out of the box. We want to invite you to join us in making updates to remove barriers — starting today. Right now!

Let’s look at some changes you can make that will have an incredibly high impact toward making your sites and the web more accessible for everyone.

Use clear, descriptive, sequential headings 

Unstructured web content is overwhelming and unusable for everyone, but especially for people with cognitive disabilities and those who use screen readers. Headings organize content and guide readers through your site. 

Your headings should make it easy to skim a page and get a clear purpose and overview of content without having to read body copy. 


  • Use heading levels to show visual differences
  • Use heading text just to be compliant — make sure it’s useful 


  • Use one H1 per page that describes its purpose (or only use multiple H1s when a page truly has more than one purpose)
  • Nest headings in order (e.g., H3 under H2)

To learn more about the importance of organizing your content with headings and how to style headings in Webflow, check out this section on headings in Webflow University’s video lesson on Advanced web typography.

Apply recommended color contrast ratios

Sufficient color contrast between text and background improves the experience and legibility on your site for everyone, especially for people with vision impairments. WCAG offers suggested ratios of the best contrast based on size of text. Contrast is the difference in brightness (or luminance) between 2 colors and ranges from 1:1 (e.g., white text on a white background) to 21:1 (e.g., black text on a white background).

Color contrast guidelines for AA (minimum)

  • Text and images should have a ratio of 4.5:1
  • Large text (18 point or 14 point bold) need a ratio of 3:1

Color contrast guidelines for AAA (enhanced)

  • Text and images should have a ratio of 7:1
  • Large text (18 point or 14 point bold) need a ratio of 4.5:1

Webflow’s built-in color contrast analyzer

You can check the contrast ratio of text on your site directly from the color picker in Webflow, which displays not only the contrast ratio of text but also the WCAG level rating that corresponds to that contrast ratio.

Check the contrast ratio of text to make sure it meets accessibility standards.

Contrast ratio curve patterns

You can toggle the preview icon (the eye) under the palette on the right to see the curves for AA, AAA, and a Fail rating on WCAG. The ratio curve patterns are calculated by testing every combination of saturation and brightness for hue and opacity — watch the curves move as you adjust hue or opacity. Light text over a dark background will show an AAA rating in the upper left of the palette to Fail in the lower right, and vice versa for dark text on a light background.

Interesting: The color contrast analyzer uses an algorithm to calculate the luminosity difference between 2 colors (contrast) and rates it against WCAG guidelines for text size. The algorithm makes adjustments for font weight since bold text can be smaller and still readable. Small text needs a higher luminosity difference to be readable.

The WCAG level rating is based on the color of the background and the font size, weight, and color, which is explained with helper text that opens when you click the question mark icon. (This contrast ratio section only appears when editing the typography color of text elements.)

Note: While WCAG contrast ratio guidelines don’t apply to images (including logos), it’s best practice to apply a 4.5:1 ratio for images with prominent text. But keep in mind that images of text can be hard and often impossible for visitors with visual impairments to understand — use styled text wherever possible.

Learn more about the importance of color contrast in this section of our Webflow University video lesson on Advanced web typography.

Webflow’s built-in Vision preview

Vision impairments affect a large percentage of the population. However, if you don’t experience vision impairments, it can be difficult to imagine how your design appears to someone who does.

With Webflow’s Vision preview you can simulate how visually impaired people view your website. Use this tool at the beginning of your design workflow to make sure important information in your design isn’t conveyed only through color.

Remember: Using Vision preview provides an approximate representation of vision impairments. Factors like your own vision, the lighting you use, your screen calibration, and your operating system settings can all affect the accuracy of the previews.

Access Vision preview options by clicking Canvas settings at the top of the Designer

Choose the type of vision impairment to preview from the bottom of the Canvas settings modal.

You can choose from:

  1. Red-green color blindness (Green weak, Green blind, Red weak, and Red blind previews)
  2. Blue-yellow color blindness (Blue weak and Blue blind previews)
  3. Full spectrum color blindness (Color weak and Monochrome previews)
  4. Focus impairment (Blurred vision preview)

The vision impairment you’ve selected is indicated by an icon to the right of the Canvas settings

To stop previewing your design from a vision impaired perspective, click Canvas settings again and change the Vision preview to None.

Note: Due to a Safari bug, Vision preview isn’t available in Apple’s browser. The bug specifically relates to Safari not applying CSS filters with url() values to iframes. Webflow has brought the bug to Apple’s attention, though no tracking number was provided. Alternatively, you can use Vision preview with Firefox and Chrome browsers.

Use clear, visible form labels and help text

Form elements with in-field placeholder text that disappears when you input information make it hard for people with (and without) cognitive disorders to remember what a form is asking. A simple solution is to always use form labels and help text that stays visible.

In Webflow, this currently requires a custom solution. You can use the label element in the Designer for your form’s input, text area, and select fields. Make sure you insert the label first, and then name your form field the same as your label text. 

To name your form field: 

  1. Select your form’s text field
  2. Open the Element settings (press D on the keyboard)
  3. Name your field the same as your label text

A great way to reuse your form elements is to group the related label and field together.

To group your label and field together in Webflow:

  1. Open the Add panel (press A on the keyboard)
  2. Drag a Div block into your form element
  3. Drag your related label and field into the Div block (making sure to place the label above the field element)

Now you can copy the Div block (Command + C on Mac or Control + C on Windows) and paste it (Command + V on Mac, Control + V on Windows) in your form, and rename the copied label and field to reuse them.

Along with helping visitors recall the purpose of the field, a clear label outside the input field will better meet color contrast settings for visually impaired visitors (since placeholder text is usually a light color). It also gives screen readers access to a proper label to announce.

Use meaningful button and link names

Screen readers can give visitors an overview of all the links on a page. When links are read out of context in a list, it's important they tell readers:

  1. What the link is
  2. Where it's taking them


  • Embed links in generic terms like “more,” “this page,” or “click here”
  • Link to raw URLs


  • Embed links in clear, specific language that tells people where the link will take them and why they might want to go there
  • Indicate if a link will open high-bandwidth media like a PDF or video within the linked text

For an example of a screen reader announcing unhelpful links on a page, check out in this section about links on Webflow University’s video lesson on Advanced web typography.

Use thoughtful motion and animation

Certain webpage animations and flashing content can negatively affect the health and well-being of people with vestibular and photosensitivity disorders. This can include triggering motion sickness and seizures. When working on your designs, it’s best to think about accessibility from the start, and create safe animations that don’t cause harm from unexpected or excessive movement or flashing. 


  • Ensure any blinking or flashing doesn’t happen more than 3 times per second to prevent seizures, and remove any harmful flashing content 
  • Ensure your animation has a positive usability impact (e.g., the animation directs users to key content), but also provide alternatives for users who choose to remove or reduce animation (e.g., use static images rather than moving images) 
  • Ensure that no valuable information is lost for visitors who choose to disable motion 
  • Provide and show controls to pause and/or stop moving or blinking elements that start automatically and last more than 5 seconds in parallel to other content (e.g., a slide carousel) 

Check your design

You can test what your designs look like with reduced motion by toggling the reduced-motion setting on your device or browser. Read about how to enable and disable reduced motion settings to perform this test.

Include alt text for every important image

Images can't be seen by blind visitors. Alt (alternative) text is an attribute that lets you provide text-based descriptions for images. Alt text is also displayed when an image doesn't load properly. 

To add alt text to any image:

  1. Open the Assets panel (press J on the keyboard)
  2. Click the cog icon that appears when you hover over the image that needs alt text
  3. Write a description in the Descriptive field

This alt text will be used any time this asset is used in your project.

General guidelines for alt text:

  • Include alt text for every important image you upload (including logos)
  • Write a concise description that calls out important visual features
  • Avoid repeating surrounding text
  • Leave out the words "image" or "picture"  
  • Add a space in the alt field for purely decorative images so the screen reader doesn't announce it

As an example, here’s the alt text photographers from “Disabled and Here” provide for the stock photo below: Six disabled people of color smile and pose in front of a concrete wall. Five people stand in the back, with the Black woman in the center holding up a chalkboard sign reading "disabled and here." A South Asian person in a wheelchair sits in front.

We recommend including alt text in the Asset manager to make sure text is always included on dynamic images, like in a Collection list. But you can also add alt text as you add images to your project in case the context of the image is different for a specific instance.
