Tooltip react Code Snippet in 2024

Renders a tooltip component.

• Use the useState() hook to create the show variable and initialize it to false.
• Render a container element that contains the tooltip element and the children passed to the component.
• Handle the onMouseEnter and onMouseLeave methods, by altering the value of the show variable, toggling the className of the tooltip.

.tooltip-container {
  position: relative;
}

.tooltip-box {
  position: absolute;
  background: rgba(0, 0, 0, 0.7);
  color: #fff;
  padding: 5px;
  border-radius: 5px;
  top: calc(100% + 5px);
  display: none;
}

.tooltip-box.visible {
  display: block;
}

.tooltip-arrow {
  position: absolute;
  top: -10px;
  left: 50%;
  border-width: 5px;
  border-style: solid;
  border-color: transparent transparent rgba(0, 0, 0, 0.7) transparent;
}

const Tooltip = ({ children, text, ...rest }) => {
  const [show, setShow] = React.useState(false);

  return (
    <div className="tooltip-container">
      <div className={show ? 'tooltip-box visible' : 'tooltip-box'}>
        {text}
        <span className="tooltip-arrow" />
      </div>
      <div
        onMouseEnter={() => setShow(true)}
        onMouseLeave={() => setShow(false)}
        {...rest}
      >
        {children}
      </div>
    </div>
  );
};

ReactDOM.render(
  <Tooltip text="Simple tooltip">
    <button>Hover me!</button>
  </Tooltip>,
  document.getElementById('root')
);
