Why Do Inline-Block Elements Misalign Vertically, and How Can I Fix It?

Inline-Block Element's Vertical Alignment Discrepancy

Why does an inline-block element with content exhibit vertical misalignment?

Explanation:

The CSS property vertical-align by default aligns the element's baseline with the parent element's baseline. If the element has no in-flow line boxes or its overflow property is not visible, the baseline aligns to the bottom margin edge.

In the provided example, the .divAccountData element initially lacks content. As a result, its baseline aligns to the bottom margin edge of its parent, causing misalignment with the .divAccountPicker element.

Solution:

To vertically align both elements, set the vertical-align property of the .divAccountData element to top:

.divAccountData {
  vertical-align: top;
  /* Other CSS properties... */
}

This ensures that the baseline of the .divAccountData element aligns with the top edge of the .divAccountPicker element.

Additional Considerations:

• The issue can also be resolved by adding text to the .divAccountData element, which establishes an in-flow line box and resets the baseline.
• The baseline alignment is affected by the number of lines in each element. If the number of lines varies, forcing vertical alignment using vertical-align: top on both elements is necessary.
