Border Utilities

You can use the border attribute to add a border.

Border Color

You can use the border-{color}-{number} to control the border element:

export default function Home() {
  return (
    <>
      <div className="border border-blue-500">Blue border</div>
      <div className="border border-green-500">Green border</div>
    </>
  );
}

Border Width

You can set the border width using the border-{number} utilities:

export default function Home() {
  return (
    <>
      <div className="border border-blue-500">Text</div>
      <div className="border-2 border-blue-500">Text</div>
      <div className="border-4 border-blue-500">Text</div>
      <div className="border-8 border-blue-500">Text</div>
    </>
  );
}

Border Style

You can use border-{style} to control the border style of an element:

export default function Home() {
  return (
    <>
      <div className="border border-blue-500 border-solid">Text</div>
      <div className="border border-blue-500 border-dashed">Text</div>
      <div className="border border-blue-500 border-dotted">Text</div>
      <div className="border border-blue-500 border-double">Text</div>
    </>
  );
}

Border Radius

You can control the border radius by using utilies like rounded, rounded-md, rounded-lg and rounded-full.

Example:

export default function Home() {
  return (
    <>
      <div className="border border-blue-500 bg-blue-500 size-32 border-solid rounded">Text</div>
      <div className="border border-blue-500 bg-blue-500 size-32 border-solid rounded-md">Text</div>
      <div className="border border-blue-500 bg-blue-500 size-32 border-solid rounded-lg">Text</div>
      <div className="border border-blue-500 bg-blue-500 size-32 border-solid rounded-full">
        Text
      </div>
    </>
  );
}
