Twine 2 Harlowe CSS Stylesheet

I am still awfully new at learning CSS and fear for creating a proper Stylesheet to fit Harlowe's Story Format. If someone could turn the following Stylesheet originally made for Sugarcane, it would help me admire what I need to do and what I need to do differently:

body {
background:LightGrey;
color: #000;
font: medium "Times New Roman", Times, serif;
margin: auto;
padding: 8px;
}
#passages {
margin: auto;
border: 0;
padding: 0;
}
.header, .footer {
border: 1px inset;
margin: 0.5rem auto;
}
.passage {
font: inherit;
line-height: inherit;
margin: auto;
}
.passage ul {
padding: 0;
text-align: left;
}
.passage li {
display:inherit;
margin: 0;
}
a, #sidebar #snapback, #sidebar #restart, #sidebar #share, .menu div {
font-weight:inherit !important;
text-decoration: underline !important;
color: #00F !important;
}
a.visited {
color: #7F007F;
}
#sidebar {
font: inherit !important;
position:static;
width: auto;
list-style: disc outside;
}
#sidebar ul {
padding: inherit;
}
#sidebar li {
color: inherit;
text-align:inherit;
margin:inherit;
display:inline;
}
#sidebar #titleSeparator {
display:none;
}
#sidebar #title, #sidebar #title:hover {
color:inherit;
}
#sidebar #storyTitle, #sidebar #storyTitle:hover {
font-size: 2rem;
margin: .67rem 0;
font-weight:bold;
}
#sidebar #storySubtitle {
font-size: inherit;
font-weight:bold;
}
#sidebar #storyAuthor::before {
content: "by ";
}
#sidebar #storyAuthor {
font-size:medium;
display:block;
font-weight:bold !important;
}
#sidebar #credits {
display:block;
font-size: smaller;
padding: inherit;
}
#snapbackMenu::before {
content: "Rewind to:";
font-weight:bold;
}
#shareMenu::before {
content: "Share this story at:";
font-weight:bold;
}
.menu::before {
content: "Rewind to:";
font-weight:bold;
}
.menu, .menu div:hover {
position: static;
background-color:inherit;
color:inherit;
opacity:1;
border:0;
font:inherit;
line-height:inherit;
}
.menu div {
margin: 0 1.12rem;
display: list-item;
list-style:disc outside;
}
