Creating visually appealing and well-structured PDFs is crucial for presenting information in a professional manner. TCPDF is a popular PHP library used to generate PDFs, and Magento 2 developers often encounter issues when trying to apply custom styling to their documents. In this blog post, we will delve into the common problem of margin and padding styling not working in TCPDF, and provide a detailed guide on how to address this issue in your Magento 2 application. Let’s dive in!
The Problem: Margin and Padding Not Working
When using TCPDF to generate PDFs in Magento 2, you may encounter issues with margin and padding styling not being applied to your HTML elements. Despite using inline styles and setting the appropriate values for margins and paddings, the resulting PDF may not display the expected layout.
Understanding TCPDF’s Styling Limitations
TCPDF is a powerful library, but it has some limitations when it comes to styling. Not all CSS properties are supported, and certain styles, such as margin and padding, may not be applied as expected. To overcome these limitations, we need to adopt alternative approaches for controlling the layout and spacing of elements in our PDFs.
Alternative Solutions to Style Your PDFs
1. Using Tables and Cells
One way to control the layout and spacing in your TCPDF-generated PDFs is by using tables and cells. You can create table structures and use the cellpadding and cellspacing attributes to control the spacing between elements. For example:

2. Applying Custom CSS
While TCPDF may not support all CSS properties, you can still use custom CSS to style your PDFs. Try creating a separate CSS file and using the writeHTML() method to include it in your PDF, like so:
$css = file_get_contents('path/to/your/custom.css');
$pdf->writeHTML($css, true, false, true, false, '');
Keep in mind that not all CSS properties will work, so you may need to experiment with different combinations to achieve the desired layout.
3. Experimenting with Line Breaks and Spacing
Sometimes, a simple solution like adding line breaks (<br>) or non-breaking spaces ( ) can help you achieve the desired spacing and layout in your PDFs. This approach may not be ideal for complex layouts, but it’s worth trying if you’re looking for a quick fix.
Conclusion
Although TCPDF has some limitations when it comes to styling PDFs, there are alternative methods you can use to achieve the desired layout and spacing in your Magento 2 application. By using tables and cells, applying custom CSS, or experimenting with line breaks and spacing, you can create visually appealing and well-structured PDFs that meet your needs. Happy coding!
