Working with CSS
Snowman 1.X uses a simple set of CSS rules for displaying HTML content. These can easily be extended or overwritten through adding new style rules within the Story Stylesheet when using the Twine 2 editor or as part of a stylesheet-tagged passage when using a Twee compiler.
Link Styles Example
Snowman uses the following rules for all <a> links:
a {
    color: #222;
    text-decoration-color: #bbb;
}
a:hover {
    color: #cc8929;
    text-decoration-color: #cc8929;
}
a:active {
    color: #ffb040;
    text-decoration-color: #cc8929;
}
These can be directly overwritten using new a{} rules, but more specific overriding of their rules could take place by targeting the a elements within the element with the class passage instead. (See Elements for more details about Snowman HTML structure.)
For example, the following would the most specific targeting of links within a Snowman 1.X story:
.passage a {
  // CSS rules
}
