CSS selectors are more powerful than most developers realize. Beyond the basics, advanced selectors help you write cleaner, more efficient code and reduce your reliance on complex JavaScript.

Here are 5 selectors every frontend dev should be using:

1️⃣ :has() – The Parent Selector

Example:

article:has(img) {
  border: 2px solid #4caf50;
}

👉 Style elements based on their children — no JS hacks needed!

2️⃣ :where() – Low Specificity Power

Example:

:where(h1, h2, h3) {
  color: #333;
}

👉 Write powerful fallback rules with zero specificity headaches.

3️⃣ The ~ General Sibling Combinator

Example:

h2 ~ p {
  margin-top: 0;
}

👉 Target all following siblings, not just the immediate one.

4️⃣ :not() – Exclude Elements Smartly

Example:

nav li:not(.active) {
  opacity: 0.7;
}

👉 Style all elements except certain ones — super clean targeting.

5️⃣ Attribute Selectors with Wildcards

Example:

a[href^="https"] {
  color: green;
}

👉 Target links starting with “https” — useful for external/internal linking styles.
