    text-wrap-style: balance;
    line-clamp: 3;
    /* This code is unnecessary in any browser that supports the unprefixed version of line-clamp,
       but neither does it have any detrimental effect,
       and it broadens the test to browsers that only support the prefixed version */

<p>Test passes if the box with a blue frame is identical to the orange one.
