justified—text is aligned along the left margin, with letter-spacing and word-spacing adjusted so that the text falls flush with both margins, also known as fully justified or full justification; centered—text is aligned to neither the left nor right margin; there is an even gap on each side of each line.
The margin helps to define where a line of text begins and ends. When a page is justified the text is spread out to be flush with the left and right margins. When two pages of content are combined next to each other (known as a two-page spread), the space between the two pages is known as the gutter. [2] (Any space between columns of text is a ...
In no case should the resulting font size of any text drop below 85% of the page's default font size. The HTML <small>...</small> tag has a semantic meaning of fine print or side comments; [2] do not use it for stylistic changes. For use of small text for authority names with binomials, see § Scientific names.
Justified typesetting varies the spaces between words from a pre-defined passage of text so they line up with the edges of the page. An example of justified typesetting with a monospace font would look like this. Showing that you can vary the words in a piece of text to make it look justified is pointless.
It's used a lot in math, since all usual variables|math variables are italic and serif both. For folks not conversant with mathematical typesetting rules, it probably seems like fluff, even though for us inside mathematics, the ubiquitous use of an italic serif font for most (but not all) single-letter symbols makes it a huge time-saver.
Both are encoded as characters in the General Punctuation code block of the Unicode character set as U+2000 EN QUAD and U+2001 EM QUAD, which are also defined to be canonically equivalent to U+2002 EN SPACE and U+2003 EM SPACE respectively. [2] [3] [4] LaTeX markup uses \quad for an em quad, and has other related whitespace escape sequences. [5]
The default alt text is the LaTeX markup that produced the image. You can override this by explicitly specifying an alt attribute for the math element. For example, <math alt="Square root of pi">\sqrt{\pi}</math> generates an image π {\displaystyle {\sqrt {\pi }}} whose alt text is "Square root of pi".
The TeXmacs text editor is a WYSIWYG-WYSIWYM scientific text editor, inspired by both TeX and Emacs. It uses Knuth's fonts and can generate TeX output. Overleaf is a partial-WYSIWYG, online editor that provides a cloud-based solution to TeX along with additional features in real-time collaborative editing.
