Variations
Accessibility
Keyboard Accessible
Users are able to use the keyboard to navigate through focusable content using the ‘Tab’ key to navigate/focus and ‘Enter’ or ‘Spacebar’ to activate.WCAG 2.1.1: Keyboard This navigation is done in sequential and logical order. WCAG 2.4.3: Focus Order
Hover and Focus State
Actionable items have distinctive styling on hover/focus to provide a visual cue to the user that the element is focused and there is an action that can be taken. WCAG 1.4.13: Content on hover or focus
Color Contrast
A contrast ratio of at least 4:5:1 between text and background color is ensured to enhance readability. WCAG 1.4.3: Contrast (minimum)
Responsive
The component scales in relation to the to the screen size to prevent truncating content and reflows properly when zoomed up to 200% without horizontal scrolling WCAG 1.4.10: Reflow
Consistent
Styles are applied consistently including line height, font style, weight, spacing and color of text. WCAG 1.4.12: Text Spacing
Logo
Provide effective alt text of the logo that is concise and relevant. Avoid phrases like “image of” since screen readers often already announce the type of element. WCAG 1.1: Text Alternatives
Optional Link
Use effective text to describe what the link is and where it is taking the user. This should be clear, descriptive text that conveys the link content succinctly and the purpose and destination of the link. WCAG 2.4.9: Link Purpose (Link Only)
- Example of effective text (preferred): Learn more about Innovate Maryland
- Example of generic text (avoid): Learn more
Disclaimer: If the visible link text is not sufficiently descriptive, you can use an aria-label attribute to provide additional context for screen reader users. The aria-label should clearly describe the link's purpose and destination.
- If the visible text is not necessary for screen readers (e.g., it's redundant or less descriptive), consider using aria-hidden="true" on the visible text element. This ensures that screen readers will prioritize the aria-label.
Example with aria-label and aria-hidden:
<a href="https://example.com/innovate-maryland" aria-label="Learn more about Innovate Maryland"> <span aria-hidden="true">Learn more</span> </a>
This ensures that the link is accessible while maintaining concise visible text.
Layout
- Show a maximum of 4 logos per row on a home or landing page and a maximum of 3 when width is limited by layout (interior pages).
- If an uneven number of logos is entered.
- Logo images may have an optional link.
- Logos/graphics should maintain size balance in relation to each other.
- There is no minimum or maximum for numbers of logos.
