/* NOTE @2021.07.23
 * The `img + em` method for image caption:
 *
 * Taken from: https://stackoverflow.com/a/30366422
 *
 * In markdown, we can write:
 *
 *     ![][path/to/image]
 *     *image_caption*
 *
 * This would generate the following HTML:
 *
 *     <p>
 *         <img src='path/to/image' alt/>
 *         <em>Image caption</em>
 *     </p>
 *
 * Now, in CSS, we can use the `img + em` selector to
 * modify the caption style, as shown as follow:
