CSS selectors all exist within the same global scope. Anyone who has worked with CSS long enough has had to come to terms with its aggressively global nature—a model clearly designed in the age of documents, now struggling to offer a sane working environment for today’s modern web applications. Every selector has the potential to have unintended side effects by targeting unwanted elements or clashing with other selectors. More surprisingly, our selectors may even lose out in the global specificity war, ultimately having little or no effect on the page at all.

Any time we make a change to a CSS file, we need to carefully consider the global environment in which our styles will sit. No other front end technology requires so much discipline just to keep the code at a minimum level of maintainability. But it doesn’t have to be this way. It’s time to leave the era of global style sheets behind.

It’s time for local CSS.

Many years ago, I worked for my parents who own a video production company. Because it is a family business, you inevitably end up wearing many hats and being the czar of many different jobs. I mainly managed projects and worked as a video editor. On production, there were times that I was called on to work as an audio tech and was made to wear headphones on long production days. In those days, having a really good set of headphones that picked up every nuance of sound was essential to making sure the client got what they needed.

It’s safe to say that because of my unique professional experiences, I’ve tested out a lot of headphones.

First impressions.

Naturally, my first impression of these headphones is based off of the look of them. They have a classic over-the-ear style that is highlighted by a blue LED light that indicates the power for the noise canceling. The padding on the ear pieces seems adequate for extended usage periods.

Naturally, my first impression of these headphones is based off of the look of them. They have a classic over-the-ear style that is highlighted by a blue LED light that indicates the power for the noise canceling. The padding on the ear pieces seems adequate for extended usage periods.

They are wired headphones, but the 3.5mm stereo mini-plug cable is detachable. Something else I noticed right of the bat was the very nice carrying case that comes with them. It has a hard plastic exterior with a soft cloth interior that helps to protect the surface of the headphones from scratches. I never truly appreciated cases for headphones until I started carrying them from place-to-place. Now I can’t imagine not having a case.

It’s funny—the thing I feared would take away my “freedom” is the one thing that has allowed me to have it.
