* * * ``` * * ### Initial Splitter Position * * The initial splitter position is determined from the sizes of the content elements * inside the split layout. Therefore, changing `width` on the content elements * affects the initial splitter position for the horizontal layouts, while `height` * affects the vertical ones. * * Note that when the total size of the content elements does not fit the layout, * the content elements are scaled proportionally. * * When setting initial sizes with relative units, such as percentages, it is * recommended to assing the size for both content elements: * * ```html * *

Three fourths

One fourth

* * ``` * * ### Size Limits * * The `min-width`/`min-height`, and `max-width`/`max-height` CSS size values * for the content elements are respected and used to limit the splitter position * when it is dragged. * * It is preferred to set the limits only for a single content element, in order * to avoid size conflicts: * * ```html * *
