What is align-self?

align-self overrides the flex container's align-items setting for a specific flex item. It applies to individual items, not the container.

align-self Values

Accepts the same values as align-items:

auto — inherits container's align-items (default)
flex-start — aligns to cross start
flex-end — aligns to cross end
center — centers on cross axis
stretch — stretches to fill cross size
baseline — aligns text baselines

Practical Example

A navigation where most items are centered but the last button is aligned to the end:

<nav class="nav">
  <span>Logo</span>
  <a href="#">Link</a>
  <button class="cta-button">Sign Up</button>
</nav>

Stretching One Item

Make one card stretch to full height while others shrink-wrap:

<div class="sidebar-layout">
  <div>Content</div>
  <div class="ad-unit">Ad</div>
</div>

margin: auto as Alignment

Auto margins on flex items push themselves (or siblings) to the opposite side. This is a powerful alternative to align-self for centering or distributing space.

<nav class="nav">
  <span class="logo">Logo</span>
  <a href="#">Home</a>
  <a href="#">About</a>
  <span class="settings">&#9881;</span>
</nav>

margin: auto Vertical Centering

Auto margins work vertically too. margin-top: auto inside a column flex container pushes an element to the bottom:

<div class="card">
  <p>Card body</p>
  <div class="card-footer">Footer</div>
</div>

Baseline Alignment

Aligning items by text baseline keeps readable relationships between items of different sizes:

<div class="stats-row">
  <span class="big-number">42</span>
  <span class="label">users</span>
</div>

align-self: auto (Default)

align-self: auto tells the item to use the container's align-items value. You only need to set align-self when you want to deviate from the container's default.

Cross Axis vs Main Axis

Remember: align-self always operates on the cross axis. If flex-direction: column, the cross axis is horizontal, so align-self controls left/right positioning.

Combining align-self with flex-grow

A common pattern: grow an item to fill space AND override its cross alignment:

<div class="features">
  <div class="feature-card">Feature A</div>
  <div>Feature B</div>
</div>

Grid vs Flexbox Alignment

CSS Grid has both align-self (row axis) and justify-self (column axis) for 2D control. Flexbox's align-self only controls the cross axis — use margin: auto for the main axis.

Quick Check

A flex container has align-items: center. One item needs to align to the top of the cross axis. What property should you set on that item?

Recap

align-self overrides the flex container's align-items for individual items. Use it to break the alignment pattern for specific elements. margin: auto is a complementary tool that distributes remaining space to push items along either axis.
