Answer : display:inline-block will not create a float issue so there is no need to add clearfix you can also use overflow:hidden instead of display:inline-block .header { display: inline-block; width: 100%; border: 1px solid red; } .playerOne { float: right; } .playerTwo { float: left; } <div class="header"> <div class="playerOne"> Oli </div> <div class="playerTwo"> Matt </div> </div> make it simple with flex .wrapper{ display: flex; justify-content: space-between } <div class="wrapper"><span>1</span><span>2</span></div> The problem is that you are not targeting the proper inline-block element. :) .header > div{ display: inline-block; } .playerOne{ float:right; }

Answer : My recommendation is a hitherto-little known gem, called ScreenShade. There are several decent Mac software screen dimmers out there, of which I've found the ones whose dimming method is to apply an increasingly opaque black 'overlay' over the screen to be the most superior in appearance (providing much higher quality 'low blacks' than Shades which does its dimming via color profile/gamma level tweaking) and in doing so, also playing nice with famous color temperature regulating app, f.lux. The best examples in this group, are Shady (whose development has been abandoned by its dev and has a no better rogue clone in the Mac App Store), ScreenDimmer, Screen Shade, and Work at Night. (N.b. these last two, confusingly appear to be clones, by the same dev on the Mac App Store.) But if you're looking to more fully emulate the Mac's in-built hardware dimming in software, you're looking for an app that can have the dimming triggered via hotkey...

Answer : What Dell calls "Premier Color" and HP calls "Dreamcolor" is marketing-speak for 10-bits per channel color. They are also pre-calibrated with a selection of color profiles for professional work in (especially) video and television, also applicable to photography and graphic design, which you can find in their specs. You can use the full capabilities of a 10-bit monitor only if you have an OS that supports it and have a professional-grade GPU that will output 10-bit color. There is a good answer here with more details on that topic. Unless you are doing truly color-critical work, the extra color depth and color presets may not be worth the extra cost, but it's worth noting that they can display sRGB, Adobe RGB (almost!), and several television standards, which are not achievable with the usual 8-bit/channel displays. The details are, frankly, highly technical and tl;dr for most purposes. If you Google "10 bit displays" you'll find a...
