The `Tooltip` component wraps a string of text and reveals a small bubble of additional context on hover or keyboard focus. Tooltips can include an optional headline and a call-to-action link. Tooltips stay inside the viewport: when the wrapped term sits near a screen edge the bubble shifts to fit, and when there is no room above it flips below the term. On touch screens, tap the term to open the tooltip and tap anywhere else to dismiss it. ## Usage You can use the Tooltip component directly within your MDX files without any import: ```html Every API endpoint is documented on its own page. ``` Every API endpoint is documented on its own page. ## Headline and call to action Add a bold headline above the tip text with `headline`, and append a link with `cta` and `href`.
