Can Opera display pages that use DHTML?
Opera has excellent support for ECMAscript (standardised Javascript), CSS, and HTML, the key languages combined by authors to create dynamic pages, so it is indeed possible for Opera to display dynamic content within a document. There are some limitations however; Unlike some current desktop browsers, Opera 5 cannot usually alter the structure of a Web page once it has been drawn. This means that increasingly popular DHTML techniques such as inserting or replacing whole paragraphs and table rows when you hover over an element do not work in Opera. This functionality will be implemented in future versions, but for Opera 5 the most reliable way to control which elements are visible to the user is to manipulate the CSS visibility property. Dynamically updating the contents of form elements is possible in Opera, as are image-swapping effects, and although you can’t change the structure of elements once they are drawn you can change their background, text and border colours.
