## Using HTML
You can use most HTML tags in TWiki topics without a problem. This is useful where you want to add some content that is formatted in a way that is not supported using [[TWiki shorthand|Main/WebHome#TWikiShorthand]], for example, you can write `deleted text` to get deleted text.
There are a few usability and technical considerations to keep in mind:
- On collaboration pages, it's better **not** to use HTML, but to use [[TWiki shorthand|Main/WebHome#TWikiShorthand]] instead - this keeps the text uncluttered and easy to edit using the plaintext editor.
- If you _must_ use HTML, use [XHTML 1.0 Transitional](http://www.w3.org/TR/xhtml1/) syntax.
- Use `
**<...>**
- of a HTML tag are on the same line, or the tag will be broken.
- In your HTML editing program, save without hard line breaks on text wrap.
When using a WYSIWYG editor, you can just copy-paste directly into the editor, and the content will be converted to [[TWiki shorthand|Main/WebHome#TWikiShorthand]] automatically when you save.
