Summary

The background-color property sets the background color of an element in PDF documents. This property is essential for creating visual distinction, highlighting content areas, and establishing document aesthetics.

Usage

selector {
    background-color: value;
}

The background-color property accepts multiple value formats including named colors, hexadecimal notation, RGB/RGBA functions, and the transparent keyword.

Supported Values

Named Colors

Standard CSS color names such as red, blue, green, white, lightgray, etc.

Hexadecimal Colors

Short form: #RGB (e.g., #f0f for magenta)
Long form: #RRGGBB (e.g., #ff00ff for magenta)

RGB/RGBA Functions

RGB: rgb(red, green, blue) where values are 0-255
RGBA: rgba(red, green, blue, alpha) where alpha is 0.0-1.0 for transparency

Transparent

transparent - Makes the background fully transparent (equivalent to rgba(0,0,0,0))

Supported Elements

The background-color property can be applied to:

Block elements (<div>, <section>, <article>)
Paragraphs (<p>)
Headings (<h1> through <h6>)
Table cells (<td>, <th>)
Table rows (<tr>)
Lists (<ul>, <ol>)
List items (<li>)
All container elements

Notes

Background colors fill the entire content area including padding but not margin
RGBA values enable semi-transparent backgrounds that blend with underlying content
The transparent keyword is useful for explicitly removing backgrounds
Background colors do not inherit from parent elements
Multiple overlapping elements with RGBA backgrounds create layered transparency effects
Background colors are rendered behind text and other content
PDF rendering maintains exact color fidelity across all viewers
For printed documents, consider color contrast and readability

Data Binding

The background-color property can be dynamically set using data binding expressions, enabling background colors to change based on model data, status conditions, or configuration settings.

Example 1: Dynamic status backgrounds in reports

<style>
    .status-badge {
        display: inline-block;
        padding: 6pt 12pt;
        border-radius: 4pt;
        color: white;
        font-weight: bold;
    }
</style>
<body>
    
    <div class="status-badge" style="background-color: ">
        
    </div>
    
</body>

With model data:

{
    "transactions": [
        { "status": "Approved", "statusColor": "#16a34a" },
        { "status": "Pending", "statusColor": "#f59e0b" },
        { "status": "Rejected", "statusColor": "#dc2626" }
    ]
}

Example 2: Conditional highlighting based on thresholds

<style>
    .data-cell {
        padding: 8pt;
        text-align: right;
    }
</style>
<body>
    <table>
        <thead>
            <tr>
                <th>Department</th>
                <th>Budget Usage</th>
            </tr>
        </thead>
        <tbody>
            
            <tr>
                <td></td>
                <td class="data-cell" style="background-color: ">
                    %
                </td>
            </tr>
            
        </tbody>
    </table>
</body>

Example 3: Themed sections with brand colors

<style>
    .section {
        padding: 20pt;
        margin-bottom: 15pt;
    }
    .section-title {
        font-size: 18pt;
        font-weight: bold;
        margin-bottom: 10pt;
    }
</style>
<body>
    <div class="section" style="background-color: ">
        <h2 class="section-title" style="color: ">Executive Summary</h2>
        <p style="color: "></p>
    </div>

    <div class="section" style="background-color: ">
        <h2 class="section-title" style="color: ">Financial Overview</h2>
        <p style="color: "></p>
    </div>
</body>

With configuration:

{
    "branding": {
        "primaryBackground": "#dbeafe",
        "primaryText": "#1e40af",
        "secondaryBackground": "#dcfce7",
