What is HTML BDO Generator?

The HTML `<bdo>` (Bidirectional Override) element overrides the browser's Unicode bidirectional algorithm and forces text to render in the specified direction. The required `dir` attribute accepts `rtl` (right-to-left) or `ltr` (left-to-right).

This is different from the CSS `direction` property or the `dir` attribute on other elements: `<bdo>` makes the browser treat each character individually and reverse their visual order regardless of the script's natural direction. It is most commonly used to display reversed or mirrored text for decorative, testing, or localisation purposes.

Frequently Asked Questions

What is the difference between <bdo> and the dir attribute?

The dir attribute on elements like <p> or <div> sets the base direction and lets the browser apply the Unicode bidirectional algorithm. <bdo> forces a hard override, reversing character order visually regardless of the script type.

Does <bdo dir="rtl"> actually reverse the characters?

Yes. With dir="rtl" the browser displays characters in reverse visual order. "Hello" appears as "olleH" on screen — the underlying HTML characters are unchanged.
