Why use Modernizr?
The goal of a reset stylesheet is to reduce browser inconsistencies in things like default line heights, margins and font sizes of headings, and so on.
The reset styles given here are intentionally very generic. There isn't any default color or background set for the body element, for example. I don't particularly recommend that you just use this in its unaltered state in your own projects. It should be tweaked, edited, extended, and otherwise tuned to match your specific reset baseline. Fill in your preferred colors for the page, links, and so on.
In other words, this is a starting point, not a self-contained black box of no-touchiness.
If you want to use my reset styles, then feel free! It's all explicitly in the public domain (I have to formally say that or else people ask me about licensing). You can grab a copy of the file to use and tweak as fits you best. If you're more of the copy-and-paste type, or just want an in-page preview of what you'll be getting, here it is.
Much of my childhood included hours spent cutting out odd shapes from folded pieces of paper and unfolding them to reveal the weirdest snowflakes I could imagine. Join me in Adobe Illustrator for a fun twist on this classic craft project.
Type Rendering Mix is useful in many situations. Let’s say you are using Proxima Novaon your website. Below you can see how the “thin” weight will look in OS X and Windows 7. Due to the way the Core Text rasterizer works, fonts will look heavier on OS X and iOS than on other platforms.
You already know that inline styles are "bad practice." Inline styles aren't reusable like CSS in separate files is, and thus, inefficient bloat. Unless of course, when it isn't. There are some instances where inline styles make perfect sense. Perhaps you have an application where user's pick their favorite color, and then you set the background of the body to that. Using an inline style in that case is actually more efficient than external CSS, since it's specific to one user and one element.
One of my least favorite parts about layout with CSS is the relationship of width and padding. You’re busy defining widths to match your grid or general column proportions, then down the line you start to add in text, which necessitates defining padding for those boxes. And ‘lo and behold, you now are subtracting pixels from your original width so the box doesn’t expand.
This chart was initially a GIF. By using animated SVGs instead of GIFs we were able to reduce our page size from 1.6 mb to 389 kb, and reduce our page load time from 8.75 s to 412 ms. That’s a huge difference.
