Microsoft Expression Web includes the capability to render web pages using a variety of different rendering engines. Importantly it includes the IE6 rendering engine so you can render pages in both IE6 and IE7 or IE8 on the same machine. We’ve now made available a free version of Expression Web SuperPreview which includes most of the functionality in Expression Web. According to the blurb:
“Expression Web SuperPreview for Internet Explorer shows your web pages rendered in Internet Explorer 6 and either Internet Explorer 7 or Internet Explorer 8, depending on which version you have installed on your machine. You can view the pages side by side or as an onion-skin overlay and use rulers, guides and zoom/pan tools to precisely identify differences in layout. You can even compare your page comp to how the targeted browsers render the page.
Expression Web SuperPreview for Internet Explorer not only shows a high-fidelity rendering of how pages will look on different browsers, but it also identifies the element’s tag, size and position, applied styles, and location in the DOM (Document Object Model) tree so you can quickly fix the error.”
Definitely worth a look.
