Small fixes

[heisenburger]

Summary

• Fixed Twitter button on webstock page
• Gave a bunch of things more padding to give important text more breathing room (readability FTW)
• Added non-zero transition times to link hover states (except for social media buttons, because those are sprites and behave in a weird way when transition time > 0)
• Slightly larger line-height for ambitious message to improve readability

Hope this helps :) Feel free to change / not use at your leisure. Best of luck for startup alley! <3
