**Performance:** The middle column is centered and has a fixed width, while the left and right columns have equal widths and adapt automatically.
**Principle:** Use a negative value for `margin` to offset the fixed width. Since it needs to be divided into two sides, just offset by half of the fixed width of the middle column.
**Problem:** Internet Explorer does not handle percentage-based width calculations well, so it may be necessary to sacrifice 1-2 pixels in display. Additionally, Internet Explorer 6 does not support minimum width.
The code is as follows:
```html
Fixed width for the middle column, equal widths for the left and right columns that adapt automatically - Beautiful Style « Style Beauty » loaoao.com
