Create a line-on-sides heading

Written byPhuoc Nguyen

A heading whose left and right sides are horizontal lines can be structured as a grid with three columns:
.heading {
display: grid;
grid-template-columns: 1fr auto 1fr;
grid-gap: 1rem;
text-align: center;
`1fr auto 1fr` indicates that the left and right columns will have the same widths and they'll take the remaining spaces.
We can use the `::before` and `::after` pseudo elements to represent the left and right sides of the heading respectively:
.heading::after {
align-self: center;
border-top: 0.25rem double #e5e7eb;
content: '';
