Design Refactoring

• removed inline styles, wherever appropriate.
• removed all layout tables (leaving just data tables).
• implemented divs for formatting.
• removed redundant IDs and replaced them with CSS classes.
• implemented a consistent pattern of HTML and CSS.
• replaced class names with a consistent naming convention (lower case and hyphens).

• We have implemented a responsive (Bootstrap) skin out-of-box.(Skin3)
• Every page has an H1 tag, giving emphasis to the most important phrase. Every shopping page, every shoppingcart page, every checkout page has an H1 tag.
• Every relevant page has a selected, primary "popping" Call-To-Action button. All buttons use CSS3.
• There are now two out-of-box style sheets - base.css (new, global) and style.css (skin-specific).
• The HTML and server controls which remain in core code now have CSS classes throughout their markup to allow them to be styled more easily.
• The traditional image headers (for tab names etc) have been replaced with CSS and string resources, making it easy to change content.
• Every form on the store has consistent class names, making it easy to style forms throughout the site. Forms work beautifully on responsive skin, too.
• CSS3 is now used - particularly on all buttons, and with media queries in use on the natively responsive skin.
• The progress bar has been removed from the multipage checkout and replaced with a CSS-managed control, with inbuilt logic to detect which page is active.
• Bill Me Later can lead to a dramatic uplift in sales - inbuilt banners help store-owners to advertise the feature .

Smart One Page Checkout (SOPC)

• SOPC now displays 'inc vat' or 'ex vat' next to shipping rates when VAT is enabled
• Customers who select 'Ok to email' during SOPC checkout will now be subscribed to the site newsletter automatically
• We updated SOPC to better handle billing addresses for purchases that don't require shipping addresses
• It was possible that the SOPC that could leave customers without a 'Place Order' button if the JS validator didn't recognize their card number format ... but not any more!
• We improved javascript issues with SOPC in IE8 and Safari
• We added an option to allow checkout through SOPC to continue even if the cart contents exceed the maximum weight allowed by realtime carriers
• SOPC no longer leaves an unneeded 'Next' button on the page during checkout
• SOPC will now alert customers when their shipping cost changes due to changes in cart contents
• We updated SOPC to better handle saving information that has already been entered when changing steps or options, leaving the page and returning, etc
• We improved the credit card number formatter and card type detection in SOPC
• SOPC now honors the DisallowShippingToPOBoxes AppConfig
• SOPC will now display the proper state choices for each country
