In typesetting, a strut is an invisible character or element, used to ensure that a text has a minimum height and depth, even if no other elements are included. For example, LaTeX and plainTeX〔 Donald E. Knuth. ''The TeXbook'' (Computers and Typesetting, Volume A). Reading, Massachusetts: Addison-Wesley, 1984. ISBN 0-201-13448-9, page 82. 〕 provide the command \strut to insert a font size specific strut. In LaTeX〔 Braams, J. and Carlisle, D. and Jeffrey, A. and Lamport, L. and Mittelbach, F. and Rowley, C. and Schöpf, R., ''The LaTeX2e Sources''. 2009/09/24, pages 19 and 129. Available online as (PDF ) and (LaTeX source ). 〕 it has a height of 70% of the baseline skip (the distance between the baselines of two consecutive lines of text) and a depth of 30% of the baseline skip. It ensures that two vertical stacked boxes which include such a strut have the same distance like two normal consecutive lines. LaTeX also supports the creation of general struts using the command: \rule() where \strut is equivalent in size to \rule().==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Strut (typesetting)」の詳細全文を読む スポンサード リンク
