The color of the underlining will remain the same even if descendant elements have different 'color' values. UAs must recognize the keyword 'blink', but are not required to support the blink effect. The property affects the vertical positioning of the element. Using the 'top' and 'bottom' alignment, unsolvable situations can occur where element dependencies form a loop. Percentage values refer to the value of the 'line-height' property of the element itself.
Negative values are possible.
The actual transformation in each case is human language dependent. The example above would put 'H1' elements in uppercase text. This property describes how text is aligned within the element. The actual justification algorithm used is UA and human language dependent. Note that alignments are relative to the width of the element, not the canvas.
