[ui] design review changes - default/primary btn colors

[ascott]

• subtle rounded corner for buttons? try 2px.
• For the top naviation bar, use a 4 pixel underline to highlight which tab is active
• use airpal blue for link color
• use blue from airpal as primary btn color
• make default btns use light bg and gray text

plz review @mistercrunch @bkyryliuk @elibrumbaugh

Can we keep the default button dark on light background? (black on light-gray?)

On the explore view we should use btn-primary only on the query button I think. Side note, the timer should become a label left of the button group.

Getting subjective here: what about a darker blue? Close to Github's blue maybe?

[ascott]

i think i prefer the airpal blue over the github blue. github blue looks too much like FB blue, and i really like that we are tying the airpal primary color over to caravel. it's nice and bright, and works well as a highlight color.

here is the explore page with dark default buttons and brighter primary for the query button.

I stacked a commit on top of your changes here, mostly dealing with a blank btn-default and using it in explore view. Oh and I moved the timer to a label.

[ascott]

can we finish discussing the changes in this pr and make the timer changes another PR?

[ascott]

i'm not sure what you mean by blank btn-default @mistercrunch

feedback from @elibrumbaugh

• let's use the brighter airpal blue
• let's nudge the stroke on hover on the nav bar up into the white bg part of the nav bar
