TLDR

In CSS, selectors combined with commas equate to an "or" effect, and :not() is for exclusion. For instance:

/* Red is for danger, be careful when you're texting or emailing! */ input[type="text"], input[type="email"] { color: red; } /* Why make checkboxes bulky? Let's keep them slim */ input:not([type="checkbox"]) { padding: 10px; }

Using the :not() pseudo-class effectively

The :not() pseudo-class works brilliantly for excluding one selector, but you can also chain multiple :not() pseudo-classes for complex exclusions:

/* Now the checkboxes and radios can breathe. Beach body ready! */ input:not([type="checkbox"]):not([type="radio"]) { border: 1px solid blue; }

In the near future, CSS4 will fine-tune the :not() pseudo-class to accept a collection of selectors, making your code more understandable:

/* Out with the old, in with the neat! */ input:not([type="checkbox"], [type="radio"]) { border: 1px solid blue; }

Mastering the cascade

Let the cascade be your wingman! Use it to apply styles, and then gracefully override them for types like checkbox:

/* Let's give all inputs a gray sweater to warm up */ input { background: lightgray; } /* But let's keep checkboxes cool, they're already hot stuff! */ input[type="checkbox"] { background: white; }

Recognizing CSS syntax limits

As magnificent as CSS is for styling, it does have its footholds. Need a lifeline for complex logical conditions? JavaScript will be there to save the day!

Verifying browser compatibility

Maintain consistency by testing your styles across various browsers. Pseudo-classes can be drama queens, showing variations in different browsers!

Calling JavaScript for backup

For conditions too daring for CSS, JavaScript might be necessary. It can cater to sophisticated "or" and "not" conditions that make CSS run for the hills!

Taming CSS specificity

Do you have a traffic jam of style conflicts? Understanding CSS specificity can bring order to the chaos. It's the traffic warden directing which style has the right of way.

Recall real-world applications

Let's give our talks a breath of fresh air with real-life applications, such as styling form inputs based on their types, or crafting theme switches that bounce classes with selectors.

Pump up the performance

Optimization isn't just a fancy word; it equates to performant styles and swift page render. Efficiency in selectors is like getting your page on the treadmill!
