            <section class="ssection"><h2>Overview</h2>

                <p><b>wexa.css</b> is a CSS framework intended to be as simple as possible to make

                    accessible web content, and to minimize the use of CSS classes for enhancing the

                    readability of HTML code, like it should always be! <b>wexa.css</b> is the main

                    CSS framework of <a class="external-link" href="https://whakerexa.sf.net">Whakerexa</a>.

                    See the <a href="wexa.html">wexa.css documentation</a> for details.

                </p>

                <p><b>book.css</b> is a CSS framework designed to make HTML content resemble a book.

                    It includes features for implementing chapters, sections, and subsections, along

                    with an auto-numbering function.

                </p>

            </section>



            <section class="ssection"><h2>The custom classes</h2>



                <p><b>book.css</b> has a built-in feature that automatically assigns numbers to chapters,

                    sections, or subsections without manual intervention. Let's show how to do it! </p>



                <p>Add the following classes into your document, and book.css does the rest: </p>

                <ol>

                    <li><code>chapter</code></li>

                    <li><code>ssection</code></li>

                    <li><code>subssection</code></li>

                </ol>



                <p>Example of use:</p>

                <pre>&lt;section class="chapter"&gt;

&lt;h1&gt; Chapter title &lt;/h1&gt;

    &lt;section class="ssection"&gt;

    &lt;h2&gt; Section title &lt;/h2&gt;

        &lt;section class="subssection"&gt;

        &lt;h3&gt; Sub-Section title &lt;/h3&gt;

        &lt;section&gt;

    &lt;section&gt;

&lt;section&gt;

                </pre>

                <p>The <code>&lt;section&gt;</code> element is used here instead of the nonsensical

                    <code>&lt;div&gt;</code>. Both will be displayed the same way, but screen readers interpret

                    a <code>section</code> in a more appropriate manner, unlike a <code>div</code>!</p>

                <p>The &lt;section&gt; element in HTML is semantic and indicates a thematic grouping of content,

                    making it useful for screen readers to understand the structure and context of the content.

                    This can assist users who rely on screen readers to navigate and understand web pages more

                    effectively. It is then perfectly suitable to indicate the chapters and sections. Fot the

                    <code>h3</code> level, the <code>section</code> can effectively be replaced by <code>article</code>.

                </p>

                <p>Notice that a proper semantic markup, including correct usage of "section", "article",

                    "header", "footer", etc., can significantly enhance accessibility for users of assistive

                    technologies like screen readers.</p>

            </section>



            <section class="ssection"><h2>The variables</h2>



                <p>Only one variable is introduced. It allows to fix the color of the numbering.</p>

            <pre>&lt;style&gt;

    :root {

        /* if you like gray */

        --numbers-color: rgb(60, 60, 60);

    }

    .dark {

        --numbers-color: rgb(180, 180, 180);

    }

&lt;/style&gt;</pre>
