Underlining Links

[ax3l]

Hi,

Thank you for this project!

I recently saw in @zingale's AMReX-Astro/Castro#3205 that underlining links is another accessibility best practice, maybe adding

/* Underline links everywhere */
.wy-nav-content a {
    text-decoration: underline;
    text-decoration-style: dotted;
    text-underline-offset: 0.15em;
}

/* Left sidebar navigation links */
.wy-menu a {
    text-decoration-line: underline;
    text-decoration-style: dotted;
    text-underline-offset: 0.15em;
}

.wy-side-nav-search a {
    text-decoration-line: underline;
    text-decoration-style: dotted;
    text-underline-offset: 0.15em;
}

to this theme could in a mild way (dotted underline) help with that?
