Are Bootstrap / Flex / CSS supported?

Chrome

Yes, as of IronPdf release version 2021.9.3678, which features our brand new pixel-perfect Chrome rendering engine.

WebKit

Using the older WebKit engine - IronPDF supports HTML 5, Bootstrap 3, and CSS3.

CSS columns and Flex are not fully supported in WebKit, so please consider alternative structures, including tables.

CSS classes that emulate Flexbox for simple use cases are table, table-row, table-cell.
