<h1>A short amsart article</h1>
</header>
<h2>Introduction</h2>
<p>This is the introduction of an amsart document. Note that paragraphs in sections
are always indented. This is different from the default latex.css styling.
</p>
<p>Here we see another indented paragraph</p>
<h3>Notes</h3>
<p>
Here we have a subsection. The heading is bolded with a period placed afterwards.
This first paragraph is displayed inline with the heading. How can I fix the alignment
so that the section heading doesn't create an extra line gap?
</p>
<p>
Subsequent paragraphs are indented as usual.
</p>
<h4>Mininote</h4>
<p> Here's a latex subsubsection. The heading is italicized in this case rather than bolded
we still have all the usual spacing elsewhere.
</p>
<h2>Main content</h2>
<p>This is another section. Again everything is indented unless the paragraph begins after
a subsection or subsubsection.

<h2>Abstract</h2>
<p>
This almost class-less CSS library turns your HTML document into a
website that looks like a
<span class="latex">L<span>a</span>T<span>e</span>X</span>
document. Write semantic HTML, add
<code class="language-html"><link rel="stylesheet"
href="https://latex.now.sh/style.css"></code>
to the <code class="language-html"><head></code> of your project and you are good to go.

</li>
<li>Done.</li>
</ul>
<h2 id="class-based-elements">Class-based Elements</h2>
<h3 id="author-abstract">Author and Abstract</h3>
<p>
Use the following code to add an author and abstract to your document.
It will look like <a href="#top">this</a>.
</p>
<pre><code class="language-html"><p class="author">John Doe <br> December 7, 2020</p>
<div class="abstract">
<h2>Abstract</h2>
<p>...</p>
</div></code></pre>
<h3 id="tdpl">Theorems, Definitions, Lemmas and Proofs</h3>
<p>
Theorems, definitions, lemmas and proofs are supported. Just wrap your
content in a div and add the corresponding class to the element like
in the following example.
</p>
<pre><code class="language-html"><div class="theorem">...</div>
<div class="definition">...</div>
<div class="lemma">...</div>
<div class="proof">...</div></code></pre>
<p>Below are some examples.</p>
<h4 id="proofs-theorems">Proofs & Theorems</h4>
<div class="theorem">
The real numbers $\mathbb{R}$ are uncountable.
</div>
<div class="proof">
If $\mathbb{R}$ is countable, then [0, 1] is countable as well. Hence
there exists a map C from $\mathbb{N}$ onto [0, 1] with
$$C(n)=\sum_{i=1}^{\infty} c_{i}(n) 10^{-i}$$ where $c_{i}(n)
\in\{0,1, \ldots, 9\},$ are the digits in decimal expansion. Now
consider a real number $$x=\sum_{i=1}^{\infty} \bar{c}_{i} 10^{-i}
\in[0,1]$$ with $\bar{c}_{i} \neq c_{i}(i)$. Obviously $C(n) \neq x$
for all $n \in \mathbb{N} .$ Hence $C$ is not onto. A contradiction.
</div>
<div class="theorem">
If $S$ is both countable and infinite, then there is a bijection
between $S$ and $\boldsymbol{N}$ itself.<sup><a href="#fn1" id="ref1">1</a></sup>
</div>
<div class="proof">
For any $s \in S,$ we let $f(s)$ denote the value of $k$ such that $s$
is the $k$ the smallest element of $S .$ This map is well defined for
any $s,$ because there are only finitely many natural numbers between
1 and $s .$ It is impossible for two different elements of $S$ to both
be the $k$ the smallest element of $S$. Hence $f$ is one-to-one. Also,
since $S$ is infinite, $f$ is onto.
</div>
<h4 id="lemmas">Lemmas</h4>
<div class="lemma">
An even number plus an even number results in an even number.
</div>
<h4 id="definitions">Definitions</h4>
<div class="definition">
A definition is a a statement of the meaning of a word or word group
or a sign or symbol.<sup><a href="#fn2" id="ref2">2</a></sup>
</div>
<h3 id="paragraphs">Paragraphs</h3>
<p>
In order to get automatic first line indentation of paragraphs, like in
default <span class="latex">L<span>a</span>T<span>e</span>X</span> articles, the class
<code>indent-pars</code> can be used with <code>article</code> tag.
</p>
<pre><code class="language-html"><article class="indent-pars">
...
</article></code></pre>
<p>
The CSS style provided follows <code>babel</code> specific language rules: by default,
the first paragraph after a section title is not indented in English, unlike Spanish and
French languages.
</p>
<p>
To avoid first line indentation of some specific paragraph, the class <code>no-indent</code>
can be used.</p>
<pre><code class="language-html"><p class="no-indent">...</p></code></pre>
<h2 id="language-support">Language Support</h2>
<p>
The labels of theorems, definitions, lemmas and proofs can be changed
to other
<a href="https://github.com/vincentdoerig/latex-css/tree/master/lang">supported language</a>
by including the following snippet, linking to the desired language in
addition to the main CSS file.
</p>
<pre><code class="language-html"><link rel="stylesheet" href="https://latex.now.sh/lang/es.css" />
...
<html lang="es"></code></pre>
<p>
Take a peek at the <a href="/languages">language support demo</a> to
see how the labels of the different languages change.
</p>
<h2 id="sidenotes">Sidenotes</h2>
<p>
Sidenotes can be used as an alternative to footnotes, where the user does not
have to jump to the bottom of the page to read it. On mobile, click the
superscript to reveal the note<label for="sn-1" class="sidenote-toggle sidenote-number"></label><input
type="checkbox" id="sn-1" class="sidenote-toggle" /><span class="sidenote">Yay, sidenotes!. If you are on
mobile, I will appear inline. If you are
using a larger screen, the sidenote will appear to the right of the
text.</span>.
</p>
<p>
Sidenotes do need a little bit of setup, they are made up of a label, an
invisible checkbox on top of the number and a span with the text inside. The
superscript is set automatically and incremented using CSS when the
checkbox has a class of <code>sidenote-number</code>.
</p>
<pre><code class="language-html"><label for="sn-1" class="sidenote-toggle sidenote-number"></label>
<input type="checkbox" id="sn-1" class="sidenote-toggle" />
<span class="sidenote"><!-- sidenote content --></span></code></pre>
<p>If you do not need superscripted numbers, you can opt out of the <code>sidenote-number</code> class and the
sidenote will not have a number assigned. On a smaller screen, you will need to add a symbol inside the
<code>label</code> for the user to click on. <label for="sn-plus" class="sidenote-toggle">⊕</label><input
type="checkbox" id="sn-plus" class="sidenote-toggle" /><span class="sidenote">This is a sidenote without a
number.</span>
</p>
<p>The snippet for a sidenote without a number is very similar:</p>
<pre><code class="language-html"><label for="sn-anything" class="sidenote-toggle">⊕</label>
<input type="checkbox" id="sn-anything" class="sidenote-toggle" />
<span class="sidenote"><!-- sidenote content --></span></code></pre>
<!-- sidnotes as a link
<label for="sn-plus" class="sidenote-toggle"><a
href="#sn-plus-content">⊕</a></label><input type="checkbox" id="sn-plus" class="sidenote-toggle" /><span
class="sidenote" id="sn-plus-content">This is a sidenote without a number.</span> -->
<p>Add a class of <code>left</code> to the span with the <code>sidenote</code> class to make the note appear on
the left side of the page on instead of right.</p>
<p>The symbol you could use to indicate a sidenote is up to you. What about this notebook. <label for="sn-symbol"
class="sidenote-toggle">📝</label><input type="checkbox" id="sn-symbol" class="sidenote-toggle" /><span
class="sidenote left">A notebook indicating a note. Aha. <br> (if on a large screen, resize to mobile to see
the emoji)</span></p>
<!-- <blockquote>You could also have sidenotes inside blockquotes just like this one <label for="sn-quote"
class="sidenote-toggle">🔖</label><input type="checkbox" id="sn-quote" class="sidenote-toggle" /><span
class="sidenote">Hello there!</span>.</blockquote> -->
<h2 id="dark-mode">Dark Mode</h2>
<p>There is built-in support for dark mode. By default, the document is in light mode. To enable dark mode, add
the
<code>latex-dark</code> class to the <code class="language-html"><body></code> element. This will force
the document to be in dark mode.
</p>
<p>If you want enable dark mode based on the
<code>prefers-color-scheme</code> CSS media query, then use the <code>latex-dark-auto</code> class instead.
</p>
<p>You can also add a dark mode toggle to your site by adding a button and a tiny bit of JavaScript:</p>
<pre><code class="language-html"><button id="dark-mode-toggle">Toggle dark mode</button></code></pre>
<pre><code class="language-javascript">document
.querySelector("#dark-mode-toggle")
.addEventListener('click', () => {
document.body.classList.toggle("latex-dark");
});</code></pre>
<p>Like this: <button id="dark-mode-toggle">Toggle dark mode</button></p>
<h2 id="alternative-typeface">Alternative Typeface</h2>
<p><span class="latex">L<span>a</span>T<span>e</span>X</span>.css uses Latin Modern by default. If you don't like
this typeface (hard to read, too thin, etc.), you can switch to the <a
href="https://github.com/alerque/libertinus"><code>Libertinus</code></a> font family by adding a class of
<code>libertinus</code> to the <code class="language-html"><body></code> tag. Click the button below to
switch between Latin Modern and Libertinus.
</p>
<button id="typeface-toggle">Current typeface: <span id="typeface">Latin Modern</span></button>
<h2 id="html-elements">HTML Elements</h2>
<p>
For a preview of all HTML elements with LaTeX.css, check out the
<a href="/elements">HTML5 elements test page</a>.
</p>
<h3 id="text-formatting">Text Formatting</h3>
<p>
This sentence is <b>bold</b>. If you like semantics, you might go with
<strong>strong</strong> or <em>emphasized</em> text. If not,
<i>italic</i> is still around. <small>Small</small> text is for fine
print. Your copy can also be <sub>subscripted</sub> and
<sup>superscripted</sup>, <ins>inserted</ins>, <del>deleted</del>, or
<mark>highlighted</mark>. You would use a
<a href="#!">hyperlink</a> to go to a new page. Keyboard input
elements like <kbd>Cmd</kbd> + <kbd>Shift</kbd>
are used to display textual user input.

<h3 id="scroll-overflow">Scroll Overflow</h3>
<p>It is best to break up long equations into smaller parts, but when this isn't possible, consider wrapping the
overflowing element with a class of <code>scroll-wrapper</code> to
allow scrolling on the x-axis. Large tables should also be wrapped with this class.</p>
<p>Below is an example of a long equation with overflow scroll.</p>
<div class="scroll-wrapper">
$$(1+x)^{n}=1+n x+\frac{n(n-1)}{2 !} x^{2}+\frac{n(n-1)(n-2)}{3 !} x^{3}+\frac{n(n-1)(n-2)(n-3)}{4 !}
x^{4}+\frac{n(n-1)(n-2)(n-3)(n-4)}{5 !}
x^{5}+\ldots$$
</div>
<h3 id="syntax-highlighting">Syntax Highlighting</h3>
<p>If you need syntax highlighting for code, LaTeX.css provides a <a href="https://prismjs.com/">PrismJS</a> theme
that immitates the <a href="https://github.com/gpoore/minted">minted</a> package for LaTeX. Add the following
stylesheet and script:</p>
<pre><code class="language-html"><link rel="stylesheet" href="https://latex.now.sh/prism/prism.css">
<script src="https://cdn.jsdelivr.net/npm/prismjs/prism.min.js"></script></code></pre>
<p>And use it like this:</p>
<pre><code class="language-html"><pre>
<code class="language-html">
<!-- your HTML code snippet -->
</code>
</pre></code></pre>
<p>Change which languages Prism highlights by customising the script <a
href="https://prismjs.com/download.html">here</a>.</p>
