html - How to apply padding to every line in multi-line text?

Question

I have background color applied to the <span> tag, there is also left and right padding set on it. The problem is: the padding is applied only to the left (beginning) and right (ending) of the <span>, not the left (beginning) and right (ending) of each line when the text is wrapped on several lines.

How can I apply the left and right padding to the middle lines?

h1 {
  font-weight: 800;
  font-size: 5em;
  line-height: 1.35em;
  margin-bottom: 40px;
  color: #fff;
}
h1 span {
  background-color: rgba(0, 0, 0, 0.5);
  padding: 0 20px;
}

<h1><span>The quick brown fox jumps over the lazy dog.</span></h1>

Answer 1

You could use box-decoration-break property with value of clone.

box-decoration-break: clone; Each box fragment is rendered independently with the specified border, padding and margin wrapping each fragment. The border-radius, border-image and box-shadow, are applied to each fragment independently. The background is drawn independently in each fragment which means that a background image with background-repeat: no-repeat may be repeated multiple times. - MDN
