Generate CSS avatar styles with initials, status indicators (online/offline/dnd), sizes, and color variants.
A CSS avatar is a styled profile picture element built entirely with CSS. When a user doesn't have a profile photo, initials-based avatars provide a clean visual placeholder. They are commonly used in user lists, comment sections, chat apps, and dashboards.
CSS avatars can include status indicators (online, offline, DND, idle) shown as a colored dot, supporting different sizes and shapes for various interface contexts. They are created using simple CSS properties like border-radius, background, and pseudo-elements.
Add a <div class="avatar">JD</div> element. If using the status indicator, include a <span class="status"></span> inside the avatar.
This generator creates initials-based avatars. For image avatars with a status dot, wrap an <img> tag in the avatar container and apply the status positioning.
Add a .avatar:hover rule to change the background color, add a glow effect, or scale the avatar with transform: scale(1.1).
Yes. The avatar uses a fixed pixel size, but you can use media queries to adjust size at different breakpoints, or use CSS custom properties for dynamic sizing.
