Cards are a cornerstone of contemporary web design, used to present information in self-contained, easily scannable blocks. Building cards that are both visually appealing and accessible to people using assistive technology (screen readers, for example) takes particular care. A well-designed card has to establish a clear visual hierarchy and be structured so keyboard focus follows a logical order, avoiding the common problem of fully clickable cards that get in the way of navigation.
This implementation uses a semantic structure built on the <article> tag to denote self-contained content. The main title uses a heading level consistent with the page, while the meta information (reading time or difficulty level, say) is formatted with a description list (<dl>), which is ideal for pairing keys and values semantically. The call to action is an explicit link acting as the card's primary destination.
Secondary interactivity, such as the button that saves or favourites the item, is handled accessibly through a <button> element with the aria-pressed attribute communicating the toggled or saved state (true or false). That ensures screen readers announce the button's state correctly, rather than relying purely on a change of color or icon, for an experience that includes everyone.
