Does anyone know any trick for backspacing, or otherwise superimposing text on text? A reliable BBcode trick would be good; but ultimately, that relies on the underlying capabilities of HTML without CSS styling tricks. A Unicode trick would work,
if it actually works.
As a Unix terminal lover, I am sad
^H^H^Hsomehow unsurprised that this old-fashioned ASCII tty trick doesn’t work
(colours are off; it is only an example):echo $'[tt][color=green]0[/color]\u0008[color=orange]\u221e[/color][/tt]' >> infsig.txt
Result:
0∞
The forum actually seems to emit a
U+0008 back to me; but the effect is not displayed in my browser. I guess that this is an HTML issue, not a forum or BBcode issue. The WHATWG HTML5 standard categorizes
U+0008 as a
C0 control that it is does not deem to be
ASCII whitespace; but I cannot so easily find the exact specification of HTML5 C0 control handling in (I guess here) HTML mode. The W3 has
a table which says that C0 controls
U+0001 –
U+0008 are allowed in HTML5 text/html, “not allowed in any way” in XML 1.0, and “allowed only as a character reference” in XML 1.1. Anyway, browser behaviour is what matters here; and if it doesn’t work in my browser, it will probably break in others’ browsers.
Thanks in advance for any tips for my quest to build a simple, aesthetically pleasing new signature.
