 ## Vertical sliders
 
+Set the `orientation` prop to `"vertical"` to create vertical sliders. The thumb will track vertical movement instead of horizontal movement.
+
 {{"demo": "VerticalSlider.js"}}
 
-**WARNING**: Chrome, Safari and newer Edge versions that is any browser based on WebKit exposes `<Slider orientation="vertical" />` as horizontal ([chromium issue #40736841](https://issues.chromium.org/issues/40736841)).
-By applying `-webkit-appearance: slider-vertical;` the slider is exposed as vertical.
+:::warning
+Chrome versions below 124 implement `aria-orientation` incorrectly for vertical sliders and exposes them as `'horizontal'` in the accessibility tree. ([Chromium issue #40736841](https://issues.chromium.org/issues/40736841))
+
+The `-webkit-appearance: slider-vertical` CSS property can be used to correct this for these older versions, with the trade-off of causing a console warning in newer Chrome versions:
 
-However, by applying `-webkit-appearance: slider-vertical;` keyboard navigation for horizontal keys (<kbd class="key">Arrow Left</kbd>, <kbd class="key">Arrow Right</kbd>) is reversed ([chromium issue #40739626](https://issues.chromium.org/issues/40739626)).
-Usually, up and right should increase and left and down should decrease the value.
-If you apply `-webkit-appearance` you could prevent keyboard navigation for horizontal arrow keys for a truly vertical slider.
-This might be less confusing to users compared to a change in direction.
+```css
+.MuiSlider-thumb input {
+  -webkit-appearance: slider-vertical;
+}
+```
 
-{{"demo": "VerticalAccessibleSlider.js"}}
+For Chrome 124 and newer, the slider includes the CSS [`writing-mode`](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_writing_modes/Vertical_controls#range_sliders_meters_and_progress_bars) property that fixes this bug.
