And one more question: I basically want to enable the "Improve legibility" and "Use real small capitals" tips from this page.

If the css argument can only be a single string, then did I do this right in my .bat file (I basically just removed all newlines)?

@kepubify-windows-32bit.exe --verbose --smarten-punctuation --fullscreen-reading-fixes --inplace --css "body {font-kerning: normal; font-variant: common-ligatures oldstyle-nums proportional-nums; font-feature-settings: "kern", "liga", "clig", "onum", "pnum";} h1, h2, h3 {font-variant: common-ligatures lining-nums proportional-nums; font-feature-settings: "kern", "liga", "clig", "lnum", "pnum";} table {font-variant-numeric: lining-nums tabular-nums; font-feature-settings: "kern", "lnum", "tnum";} code {font-variant: no-common-ligatures lining-nums; font-feature-settings: "kern" 0, "liga" 0, "clig" 0, "lnum";} .fraction {font-variant-numeric: diagonal-fractions; font-feature-settings: "frac";} element {font-variant: small-caps;} @supports not (font-variant-caps: small-caps) {element {font-variant: normal; font-feature-settings: "smcp", "onum", "pnum";}} @supports (font-variant-caps: small-caps) {element {font-variant: normal; font-variant-caps: small-caps;}}" %*

kepubify executes properly, but I have no idea if the above works and I can't seem to find the code in the kepub's css.

Edit: Ah, it's embedded in the html instead. But I still don't know if I did it right. This is what it makes inside the head tags using all of my options:

<style type="text/css" class="kobostylehacks">div#book-inner { margin-top: 0; margin-bottom: 0;}</style><style type="text/css" class="kepubify-extracss">body {font-kerning: normal; font-variant: common-ligatures oldstyle-nums proportional-nums; font-feature-settings: kern, liga, clig, onum, pnum;} h1, h2, h3 {font-variant: common-ligatures lining-nums proportional-nums; font-feature-settings: kern, liga, clig, lnum, pnum;} table {font-variant-numeric: lining-nums tabular-nums; font-feature-settings: kern, lnum, tnum;} code {font-variant: no-common-ligatures lining-nums; font-feature-settings: kern 0, liga 0, clig 0, lnum;} .fraction {font-variant-numeric: diagonal-fractions; font-feature-settings: frac;} element {font-variant: small-caps;} @supports not (font-variant-caps: small-caps) {element {font-variant: normal; font-feature-settings: smcp, onum, pnum;}} @supports (font-variant-caps: small-caps) {element {font-variant: normal; font-variant-caps: small-caps;}}</style><style type="text/css" class="kepubify-fullscreenfixes">body {
    margin: 0 !important;
    padding: 0 !important;
}

body>div {
    padding-left: 0.2em !important;
    padding-right: 0.2em !important;
}</style>

Will that actually work? Sorry for the dumb question; I'm weak on how css works.
