        <h3>💡 How to Use</h3>
        <ul>
            <li><strong>Type freely:</strong> For currency, type <code>2</code>, <code>$2</code>, or <code>$2.00</code> - all become <code>$2.00</code> when you blur</li>
            <li><strong>For percents:</strong> Type <code>15</code>, <code>15%</code>, or <code>0.15</code> - all work! The formatter handles it</li>
            <li><strong>Named variables:</strong> Use <code>data-var="TAX"</code> to create named variables that can be referenced in formulas</li>
            <li><strong>Edit easily:</strong> Click on an input to see the raw value for easy editing</li>
            <li><strong>Automatic calculation:</strong> All dependent cells update automatically when you change values</li>
            <li><strong>Mix formatters:</strong> Different cells can use different formatters</li>
        </ul>
    </div>

    <div class="info-box">
        <h3>📚 Code Example</h3>
        <p>Here's how to use formatters with input-mask behavior:</p>
        <pre>&lt;!-- Currency input with mask - accepts 2, $2, $2.00 --&gt;
&lt;input data-cell="A1" value="1234.56" data-format="currency"&gt;

&lt;!-- Named variable using data-var --&gt;
&lt;input data-cell="B1" data-var="TAX" value="0.08" data-format="percent"&gt;

&lt;!-- Use the named variable in formulas --&gt;
&lt;input data-formula="A1*TAX" data-format="currency" readonly&gt;

&lt;!-- Percent input with mask - accepts 15, 15%, 0.15 --&gt;
&lt;input data-cell="A2" value="0.08" data-format="percent"&gt;

&lt;!-- Readonly calculated field with formatting --&gt;
&lt;input data-formula="A1*1.08" data-format="currency" readonly&gt;

&lt;!-- Display-only element --&gt;
&lt;div data-formula="A1*A2" data-format="currency"&gt;&lt;/div&gt;

&lt;!-- Initialize Calx --&gt;
&lt;script&gt;
$('#myform').calx({
    autoCalculate: true
});
&lt;/script&gt;</pre>
    </div>

    <div class="info-box">
        <h3>🎨 Available Formatters</h3>
        <ul>
            <li><code>currency</code> - Formats as $1,234.56 with thousand separators. Accepts: 1234.56, $1234.56, $1,234.56</li>
            <li><code>percent</code> - Formats as 12.34%. Accepts: 0.1234, 12.34, 12.34%</li>
            <li><code>number</code> - Formats with 2 decimal places (123.46). Accepts any numeric input</li>
            <li><code>integer</code> - Rounds to whole number (100). Accepts any numeric input</li>
            <li><code>text</code> - Converts to string representation</li>
        </ul>
        <p><strong>Input-mask feature:</strong> All formatters intelligently parse your input, so you can type naturally!</p>
        <p><strong>Custom formatters:</strong> You can register your own formatters with parse() and format() methods!</p>
    </div>

    <div class="info-box">
        <h3>🎨 Conditional Styling (Style Formatters)</h3>
        <p>Apply CSS styles based on cell values using <code>data-style-if</code> attribute:</p>
        <ul>
            <li><code>negative</code> - Applies red color when value < 0</li>
            <li><code>positive</code> - Applies green color when value > 0</li>
            <li><code>zero</code> - Applies gray color when value = 0</li>
        </ul>
        <p><strong>Example:</strong></p>
        <pre>&lt;!-- Show negative profit in red --&gt;
&lt;input data-formula="REVENUE-EXPENSES"
       data-format="currency"
       data-style-if="negative"
       readonly&gt;</pre>
        <p><strong>Custom style formatters:</strong> Register your own via JavaScript!</p>
        <pre>$('#myform').calx({
    styleFormatters: {
        warning: function(value, $element) {
            if (value > 1000) {
                return {
                    color: 'orange',
                    fontWeight: 'bold'
                };
            }
            return {};
