Duplicate rulesets at lines 92 & 101:

dd {
        display: block;
        margin-left: 40px;
}
del {
        text-decoration: line-through;
}

Does this mean, that we can change these settings? E.g. the stupid purple/blue color combination for existing and visited links in Edge 😎
As I see, in Chrome Webshop we have access to (other sources) the extension "Color Links"... NOW after 100 years we may have some relief of that stupid dictatorship.
