What CSS cannot do

Your CSS can restyle nearly everything the template draws. A short list of things is refused, and a few things are out of its reach because the paper is built that way. This page is both lists, so a rule that does nothing is explained.

What is refused#

A refusal is announced. The rule is underlined in yellow in the style.css tab with the reason, at the line and column it is on, and it is counted with the notices. Only the part that is refused is left out, so the rest of the rule and of the stylesheet still applies. !important is handled the same way, below.

Anything that fetches#

@import, and any url() that is not data: or blob:, which includes a relative address. Rejarsume is local-first, and a stylesheet that fetches announces itself on every render. Paste the rules in instead, and use the Assets tab for fonts and images. See Images and fonts.

@import url("https://example.com/theme.css");

.rp-name {
  background: url("https://example.com/paper.png");
}

Anything that redefines the page#

@page, and position: fixed or position: sticky. Both would make the printed document disagree with the paginated preview, which is the one promise the preview exists to keep. The size and margins of the sheet are the Paper settings.

@page {
  size: A4;
  margin: 0;
}

.rp-name {
  position: fixed;
}

Anything that can run script#

expression(), a javascript: address in a value, and the properties behavior and -moz-binding. These were routes from a stylesheet to running code. They are long dead in current browsers and cost nothing to refuse, and an exported file can be opened years from now by a browser that is not this one.

.rp-name {
  behavior: url(script.htc);
  -moz-binding: url(script.xml);
  width: expression(1 + 1);
}

Anything that is not a plain rule#

• A rule inside a rule. CSS nesting is not supported here, and it is refused so that a brace can never close the paper's own layer early.
• @layer, because your CSS is already in the highest one.
• @charset, @namespace and @document, which do nothing here, and any at-rule not on the list below.
• A declaration written outside any rule, a rule with no selector, and a property with no value.

@layer custom {
  .rp-name {
    color: #7c2d12;
  }
}

.rp-name {
  .rp-link {
    color: #7c2d12;
  }
}

Only the line is lost#

A refusal removes only what is refused. Here the colour applies and the line that sets position is the one notice:

.rp-name {
  color: #7c2d12;
  position: fixed;
}

Missing braces#

A stylesheet with a missing brace is not thrown away. The paper says where the fault is and keeps the rules that could be read, as a browser would.

!important#

!important is removed from the copy the paper uses, and a notice is shown at the declaration. The rest of the declaration still applies. It is never needed, because your CSS is already the highest layer, and it would let a rule override the page itself.

What is allowed#

Plain rules, and these at-rules: @media, @supports, @container, @scope, @keyframes, @font-face, @counter-style, @property and @font-feature-values. Anything else is refused as not supported, because the list of at-rules grows with the web and a list of what is allowed cannot admit the next one by accident.

Custom properties and selectors of any kind are fine, and so is a url() that points at a data: or blob: address.

What CSS cannot reach#

Where a page ends#

CSS cannot move a page break. The pages are not made by the browser breaking a column. Every block is laid out once at the exact page width, measured, and then placed onto pages whole, one block after another. So an entry is never split across two pages and a paragraph is never balanced across a break, and break-inside, orphans and widows have nothing to act on. Rejarsume's own stylesheet does not use them either.

To control a page break, write ::pagebreak, set a section to start on a new page, or change Keep headings with content. All three are in Pages and breaks.

The sheet#

The width, height and margins of a page, and the clipping at its edge, cannot be overridden by a rule for .rp-page. They belong to the paper's geometry, which sits outside the layers your CSS is in, so that a stylesheet can restyle a resume but not break the pagination it was measured for. Change them with the Paper settings. See Design tokens.

Image widths#

An image's width is set on the image itself, from the paper's own controls, so a rule for the width of .rp-figure does not change it.

The web#

Your CSS cannot load a font or a picture from an address. Add the file in the Assets tab and it is part of the resume, and part of an HTML export.
