Bonanza runs all item description HTML through an HTML filter to prevent security vulnerabilities like XSS attacks. You should find that for most HTML, 95% of formatting is allowed by the HTML filter, but there are a few exceptions, including some elements that eBay allows. Unfortunately, we do not have the resources to write an HTML validation filter from scratch, so we are beholden to the limitations of our current validator, which means that when importing items from eBay there may be some differences in the appearance of your listing once it reaches Bonanza. Here is a known list of HTML that works and doesn't work:
Allowed Elements: a, abbr, acronym, address, area, b, big, blockquote, br, button, caption, center, cite, code, col, colgroup, dd, del, dfn, dir, div, dl, dt, em, fieldset, font, form, h1, h2, h3, h4, h5, h6, hr, i, img, input, ins, kbd, label, legend, li, map, menu, ol, optgroup, option, p, pre, q, s, samp, select, small, span, strike, strong, sub, sup, table, tbody, td, textarea, tfoot, th, thead, tr, tt, u, ul, var
Allowed Attributes: abbr, accept, accept-charset, accesskey, action, align, alt, axis, border, cellpadding, cellspacing, char, charoff, charset, checked, cite, class, clear, cols, colspan, color, compact, coords, datetime, dir, disabled, enctype, for, frame, headers, height, href, hreflang, hspace, id, ismap, label, lang, longdesc, maxlength, media, method, multiple, name, nohref, noshade, nowrap, prompt, readonly, rel, rev, rows, rowspan, rules, scope, selected, shape, size, span, src, start, style, summary, tabindex, target, title, type, usemap, valign, value, vspace, width, xml:lang

Special Case: background. If you include a background attribute, we will look to see if it includes a background url, and if so, we'll move it to the (allowed) "background-image" property. All other properties specified in the background property will be filtered out. If you would like to set other background properties, such as positioning and repeat, please use the individual "background-repeat" or "background-position" elements.
Limitations: Listing descriptions on Bonanza are limited to 65,000 characters (including HTML tags, newlines, etc). If your description and/or template exceeds this limit, the remainder will be cut off.
