How <div> behaves

The <div> element is a generic block-level container and is supported by every email client. However, it is far less reliable than <table> for layout purposes, Outlook Classic applies inconsistent margin and padding to divs, and several clients reset block-level styles at div boundaries. Best practice in email development is to use tables for layout and divs only for grouping styled content within a cell.

  • Outlook Classic applies margin and padding to divs inconsistently, never use a <div> for spacing critical to layout.
  • Some clients collapse adjacent divs that have background-color set when content height is zero.
  • Yahoo Mail's sanitizer occasionally rewrites class names on div elements, breaking class-based selectors.

Use <table> for any structural layout and reserve <div> for inline content grouping inside cells. Always verify Outlook rendering before relying on margin or padding applied to a <div>.
