I want .child to be perfectly centered inside .parent. Which CSS techniques can achieve this, and when would you prefer one over the other?

There are a few ways to center a .child div both vertically and horizontally inside a .parent. Here's a simple overview:

1. Absolute positioning (works well for a single child)
Set the parent to position: relative and the child to position: absolute with 50% offsets, then move it back with transform:

.parent {
  position: relative;
}

.child {
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
}

• ✅ Pros: Easy and works perfectly for one child.
• ⚠️ Cons: Can get tricky if you have multiple children or dynamic content.

2. Flexbox (most common approach)
Set the parent to display: flex and center with justify-content and align-items:

.parent {
  display: flex;
  justify-content: center;
  align-items: center;
}

• ✅ Pros: Clean, works with multiple children, and is responsive-friendly.
• ⚠️ Cons: Slightly more setup if you only have one child, but not a big deal.

3. CSS Grid
Use display: grid and place-content: center:

.parent {
  display: grid;
  place-content: center;
}

• ✅ Pros: Very readable, works well with multiple elements.
• ⚠️ Cons: Older browsers might not fully support it, but all modern browsers do.

Tip: If vertical centering isn’t working, check that the parent has a defined height. Without it, there’s nothing to center against.

Ohh great question, there are multiple way that you can have child to be perfectly centered inside .parent
For my recommendation you can use flexbox for this. Like..

.parent {
display: flex;
justify-content: center;
align-items: center;
min-height: 100vh;
}

You have choice to use min-height that will be better for height responsiveness.

On the other hand if you want to use the Position and also the transformation method you can.

.parent {
position: relative;
height: 100vh;
}
.child {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}

both are the good choice. You can use both of them..

Hope it will help you .
