Create Ecwid store stylesheet

Need to have the access to the latest Adobe Muse prerelease... [login to view URL] I working on a website using the new Adobe Muse Prerelease (fully responsive). I’m working on a site with an embedded Ecwid storefront using three Ecwid widgets from [login to view URL] The trouble is, these widgets are not yet responsive and I need them to be (the shopping cart widget, the category tabs widget and the product browser widget). • Using your skills in CSS and HTML I need these widgets to be fully responsive to browser width. Please see attached muse file with store ID already added to the widgets fly out (this is the link: [login to view URL]) • When any selection is clicked the browser re-sets so that the top of the browser is at the top of the product browser widget. I need this changed so that the browser re-sets to 100px above the category tabs widget so that all the category tabs can be seen. • In addition I require several minor CSS changes. Please see attached detailed PDF for instruction. • I would like all these changes to be written up on a document that I can then simply paste into the Adobe muse ‘insert HTML’ dialog box (like a stylesheet). This video will explain what I have been trying to achieve with the CSS alterations without success (I’m not a coder, ha ha!): [login to view URL] This is a link to an example Ecwid storefront that is fully responsive: [login to view URL] Maybe the code can be inspected and will assist? I need this done ASAP! Thanks.
