For a long time, accessibility in web design felt like a checklist. Designers would finish a mockup, run a contrast checker, and if the numbers turned green, the job was done. But the web is evolving, and so are the standards that govern it.
We are currently on the cusp of a major shift from the established WCAG 2.x standards to the upcoming WCAG 3.0 (W3C Accessibility Guidelines). While WCAG 2.1 and 2.2 are the current technical laws of the land, WCAG 3.0 represents a philosophical change. It moves away from a rigid "pass/fail" binary and toward a holistic rating system (Bronze, Silver, Gold) based on functional outcomes.
For a junior designer, this might sound intimidating. However, it is actually good news. It means the rules are moving closer to how humans actually perceive and use interfaces.
This guide will focus on the most critical element of any interface: The Button. We will explore how to design buttons that are future-proof, inclusive, and ready for the next generation of accessibility standards.
Why Button Accessibility Is the Backbone of UX
Before we discuss contrast ratios and pixels, we need to understand the stakes. In User Experience (UX) design, the button is the "verb." It is the action. It is how a user creates an account, buys a product, or submits a tax return.
If a paragraph of text is inaccessible, the user misses information. If a button is inaccessible, the user is blocked from the functionality entirely.
Accessibility is often framed as "designing for disabilities," but I prefer to think of it as "designing for variance." Users vary. They have different vision capabilities, different motor skills, and different cognitive processing speeds. They use mouses, trackpads, touchscreens, voice commands, and screen readers. A robust button design works for all of them without breaking.

Modern Button Styles: The Good, The Bad, and The Inaccessible
To understand where accessibility fits in, we have to look at the trends currently dominating Dribbble and Behance, and analyze them through an inclusive lens.
1. The Ghost Button
This is a transparent button defined only by a thin border and text. It looks elegant and minimalist.
- The Problem: Ghost buttons are notorious for poor contrast. Because they rely on the background image or color behind them, they often disappear for users with low vision. Furthermore, they lack "affordance"—they don't look clickable to users with cognitive disabilities.
2. The Floating Action Button (FAB)
Popularized by Material Design, this is the circular icon button usually found in the corner of a mobile screen.
- The Problem: While visually distinct, FABs often lack text labels. If the icon is ambiguous (like a generic "plus" sign), a user using voice control software might not know what command to speak to trigger it.
3. Neumorphism (Soft UI)
This style uses soft shadows to make elements look like they are extruded from the background.
- The Problem: This is often an accessibility nightmare. Neumorphism relies on low-contrast shadows to define edges. For a user with cataracts or a low-quality screen, a neumorphic button is invisible.
UI/UX Best Practices: The WCAG 3.0 Approach
WCAG 3.0 introduces a shift in how we measure visual accessibility, specifically regarding contrast. Here is how to apply these next-gen principles to your buttons.
1. Visual Contrast: From Ratios to APCA
Under the old rules (WCAG 2.x), we aimed for a mathematical ratio (4.5:1 for normal text). However, this math was imperfect. It didn't account for font weight or how the human eye perceives light on different backgrounds.
WCAG 3.0 is exploring the APCA (Advanced Perceptual Contrast Algorithm).
Instead of a simple ratio, APCA looks at "perceived lightness."
- The Takeaway for Designers: You need higher contrast than you think. Thin fonts need much higher contrast than bold fonts to be readable. When designing a primary button, ensure the text pops distinctly against the background color. If you are using white text on a blue button, that blue needs to be darker than you might expect.
2. Target Size and Motor Control
Fitts's Law states that the time required to move to a target is a function of the target size and distance. In simple terms: bigger is better.
WCAG 2.2 solidified the 44x44 CSS pixel minimum target size. WCAG 3.0 continues to emphasize this as a functional need for users with tremors or motor impairments.
- Design Tip: Your button visual doesn't have to be huge, but the clickable area does. You can use CSS padding to ensure that even if the button looks small, the hit-box is generous.
3. Clear State Indicators (Focus Styles)
This is where many junior designers fail. A user navigating via keyboard (using the Tab key) needs to know which button they are currently on.
- The Requirement: Never remove the default focus outline (
outline: none) without replacing it with something better. - The Design: Design a specific "Focus State" for your buttons that is as visually distinct as your Hover State. A thick, high-contrast border or a glow effect works best. Do not rely on color changes alone (e.g., light blue to dark blue), as colorblind users may not perceive the shift.
Common Mistakes to Avoid
Even experienced designers fall into these traps. Avoiding them will instantly elevate the maturity of your design work.
1. The "Click Here" Label
Buttons should describe the destination or action. A screen reader user might pull up a list of all buttons on a page. Hearing "Click Here, Click Here, Click Here" is useless.
- Correction: Use specific labels like "Download PDF," "Sign Up for Newsletter," or "Add to Cart."
2. Buttons That Are Actually Links (and Vice Versa)
This is a semantic issue that affects accessibility tools.
- The Rule: If it goes to a new URL, it is an anchor link (
<a>). If it performs an action on the current page (like opening a modal or submitting a form), it is a button (<button>). - Why it matters: Screen readers announce them differently. Telling a user to "click the button" when the software announces "link" creates confusion.
3. Relying Solely on Color
You have a green button for "Go" and a red button for "Stop." For a user with Deuteranopia (red-green color blindness), these buttons might look identical in shade.
- Correction: Always pair color with text labels or icons. For example, include a checkmark icon on the confirm button and a trash can icon on the delete button.
Tips for Designers and Developers
Bridging the gap between design and code is essential for accessibility. Here is how you can facilitate that process.
- Annotate for Accessibility: When handing off designs to developers, don't just hand off a Figma file. Add notes. Specify the "Alt Text" for icon buttons. Define the intended "Reading Order" if the layout is complex.
- Test with Your Keyboard: You don't need expensive software to do a preliminary audit. Put your mouse away. Try to navigate your design prototype using only the
Tab,Spacebar, andEnterkeys. If you get stuck, or if you can't tell which button is selected, your design has failed the basic functional test. - Design Systems are Safety Nets: If you are building a UI kit, build accessibility into the components. If you define a "Primary Button" component that already meets the APCA contrast standards and has a built-in focus state, you ensure that every instance of that button across the website is compliant by default.
Conclusion
The transition to WCAG 3.0 is a reminder that accessibility is not about passing a test; it is about human experience. It is about acknowledging that "normal" vision and "perfect" motor control are temporary states. Eventually, we all age, our eyesight degrades, and our hands get shaky.
By designing buttons that are high-contrast, clearly labeled, and generous in size, you aren't just helping users with disabilities. You are helping the mother holding a baby with one hand while trying to buy diapers on her phone. You are helping the commuter trying to read news on a tablet in bright sunlight.
As a junior designer, embracing these guidelines now will future-proof your career. It signals that you care about the quality of the interaction, not just the aesthetics of the interface. Accessibility is the ultimate form of user-centric design.
