How Can I Center a Button Inside a Div?

Centering a Button Within a Div

In web development, it's often desirable to center a button within a containing div. Let's explore two solutions to this challenge:

Using Flexbox

Flexbox provides an elegant solution for aligning elements along both axes. To center a button horizontally and vertically within a div:

#wrapper {
  display: flex;
  align-items: center;
  justify-content: center;
}

If only horizontal centering is desired, the justify-content property can be used:

#wrapper {
  display: flex;
  justify-content: center;
}

Margin-Based Approach

Without flexbox, a button can be centered using margins:

button {
  margin: -20px -50px; /* Offset to center */
  position: relative;
  top: 50%;
  left: 50%;
}

For horizontal centering only, one of these two approaches can be used:

• margin: 0 auto; on the button
• text-align: center; on the containing div
