The Short Answer
CSS float is NOT deprecated. The property remains a fully supported CSS standard with universal browser support since 2015. The confusion arises because while float exists, using it for page layouts is no longer recommended--Flexbox and CSS Grid handle those tasks far better.
Float serves one specific purpose that no other CSS property replicates exactly: wrapping text around images in a natural, flowing way. This was its original design intent, and it remains excellent at this task.
According to MDN Web Docs, float has been a baseline CSS property for nearly a decade with no signs of deprecation.

What Float Actually Does
The CSS float property places an element on the left or right side of its container, allowing text and inline elements to wrap around it. Unlike absolute positioning, floated elements remain part of the document flow.
When you float an element:
- The element shifts to the specified side of its container
- Content flows around it on the opposite side
- The element is removed from normal flow but not document flow
- Display values change--inline becomes block, inline-block becomes block
This behavior is unique to float and isn't replicated by any other CSS property, which is why it remains valuable for its specific use case. Understanding how CSS rules and rulesets work provides a foundation for grasping float's unique behavior in the cascade.

Float was designed for one specific purpose: wrapping text around images in magazine-style layouts. It worked so well that developers repurposed it for entire page layouts when nothing better existed.
This was always a hack--float was never designed for multi-column layouts. The problems were legendary:
- Parent containers collapsed to zero height
- Elements didn't align predictably
- Clearfix hacks became required knowledge
- Responsive designs were fragile and complex
As CSS-Tricks explains, this history explains why so many developers still associate float with layout problems, even though those problems were caused by misuse, not the property itself. Learning from common CSS mistakes helps avoid repeating these patterns.

Text wrapping around images, pull quotes, drop caps. Only use for its original intended purpose.
CSS Flexbox
1D layouts--navigation menus, card rows, alignment. Perfect for single-direction layouts.
CSS Grid
2D layouts--page structure, dashboards, complex grids. Best for row AND column layouts.
display: flow-root
Self-clearing containers. Replace clearfix hacks with this single property.

Use Float For:
- Wrapping text around images
- Pull quotes and callout boxes within content
- Drop caps and decorative text elements
- Sidebars where text should naturally flow around content
Use Flexbox For:
- Navigation menus and toolbars
- Card component rows
- Centering elements
- Space distribution in a single dimension
Use CSS Grid For:
- Page structure (header, sidebar, main, footer)
- Dashboard layouts
- Gallery and grid-based designs
- Any layout requiring both rows AND columns
Performance Notes
Float has excellent performance characteristics--browsers have optimized it for decades. For text wrapping, performance is never a concern. Layout recalculations with Flexbox and Grid may trigger more complex calculations in certain scenarios, but for most use cases, the difference is imperceptible.
Choose the right tool based on the problem you're solving, not performance--these differences are negligible in practice.
