i would take that small drop shadow off all the text, make the logo text align with your content box, and as a background color try going with a much much lighter grey, almost white but still noticeably grey, also maybe add a seperater between each nav link, or something to distinguish that they are different links
put the text in some sort of container maybe
A bit in your face but it'll do for now.
It's really dark.
Have a play around with the colours of the boxes you are putting your text in, also brighten the text on the navbar and perhaps consider adding a inner shadow to them.
Try colour lovers (http://www.colourlovers.com/palettes/) maybe something like this: http://www.colourlovers.com/palette/623761/Walking_Away
Is that even really information that needs to show up there though? I think changing that published/not published indicator to just read "incomplete" would be a lot better use of space unless you're anticipating there being more incomplete listings in there than completed ones?
Each one is a link to the respective category too. They look better as steps rather than just buttons.
Are all the editing pages separate pages, or are they held in tabs?
Holy screenshots batman!
• Update/Reset button text isn't centred
• Add more padding to the tabs, they need to be bigger
• Still not a fan of the dark tile background
• A lot of elements need vertically aligning (form labels, inputs) especially in the cart rows
• Step 1/2/3 isn't laid out logically, either put step two in between one and three (so they are stacked vertically) or have each step on a separate page (more traditional).
those tabs are kinda ugly
What's the span.tooltip::before?
I'm a bit of an "old-timer" when it comes to cool stuff with CSS. I started doing commercial webdev back when you still had to support IE 5.5. I still use pngfix.js on most of the sites I do and quite often will do button sprite sheets instead of rendering 100% CSS buttons. Guess I'm kind of stuck in my ways and still don't trust CSS3 support :P
I have my website scaling up nicely for MDPI devices, but how would I test it for a HDPI device like a retina iPhone for example?
