Is there a CSS not equals selector?

Putting :not() into practice

Tidy up your CSS

Instead of tagging every individual element with a class or id, you can simply use:

element:not(.irrelevantClass) {
  /* smart move, huh? */
}


This method reduces redundancy and increases clarity and productivity. That's what I call a win-win!

Combined Forces: the :not() and attribute selectors

Adding to the power of :not(), you can pair it with attribute selectors for a more Precise Targeting™ protocol:

input:not([type="checkbox"]) {
  /* because checkboxes are rebellious */ 
}


Catching the browser curveballs

While :not() has broad support, it's always a good idea to check the browser compatibility. For the old-timers that do not support :not(), consider a fallback class:

.oldschool {
  /* same groove as your :not() jazz */
}


Efficiency illustrated: Minimising CSS formality

Avoid the CSS ceremony. Using :not(), set global baseline styles and then apply the exceptions:

:not(.blues) {
  /* even without the blues, life is colorful */ 
}


This practice ensures less redundancy, trimming down your CSS from a novel to a pamphlet.

Seeking assistance from JavaScript

If CSS :not() falls short, JS can save the day with even better granularity:

$("element:not(.classToIgnore)") // jQuery


Handy for dynamic DOM manipulations based on intricate runtime conditions.

Down the dynamic route: JavaScript enhancement

Tune your Stylesheets Dynamically

Combine declarative CSS :not() with JavaScript to bring dynamic styling:

document.querySelectorAll('div:not(.dynamic)').forEach(el => {
  el.style.backgroundColor = 'green'; // enjoy your salad
});


Layer-up with Progressive Enhancement

Starting with basic :not(), layer up with JavaScript as needed for dynamic classes or interactive states. It's like adding seasoning to your coding-soup!
