// Objects that shrink to avoid floats normally use available line width when computing containing block width. However
// in the case of relative positioning using percentages, we can't do this. The offset should always be resolved using the
// available width of the containing block. Therefore we don't use containingBlockLogicalWidthForContent() here, but instead explicitly
// call availableWidth on our containing block.
if (!style()->left().isAuto()) {
if (!style()->right().isAuto() && !containingBlock->style()->isLeftToRightDirection())

} else if (!style()->right().isAuto()) {
offset.expand(-valueForLength(style()->right(), containingBlock->availableWidth()), 0);
}
// If the containing block of a relatively positioned element does not
// specify a height, a percentage top or bottom offset should be resolved as
// auto. An exception to this is if the containing block has the WinIE quirk
// where <html> and <body> assume the size of the viewport. In this case,
// calculate the percent offset based on this height.
// See <https://bugs.webkit.org/show_bug.cgi?id=26396>.
