Bold numbers in ordered lists

Windows : Internet Explorer 8.0+, Firefox 1.5+, Google Chrome, Opera 4.0+, Safari 3.1+, SeaMonkey 1.0+ [ 1 ].

Linux : Firefox 1.5+, Google Chrome / Chromium, Opera 5.0+, SeaMonkey 1.0+ [ 2 ], Hv3.

Numbers in an ordered list made bold without having any extra HTML tags added:

  1. List item
  2. List item
  3. List item



<li>List item</li>

<li>List item</li>

<li>List item</li>


CSS. Code:

ol {counter-reset: item;}

ol li {display: block;}

ol li:before {content: counter(item) ". "; counter-increment: item; font-weight: bold;}

There is no obvious way at the moment to style only numbers marking ordered list items. A workaround is to use a CSS counter instead of the default automatic numbering of ordered lists. The way a CSS counter is started allows to style specifically the marking numbers. Like in the example, where numbers in an ordered list are styled bold.

This method also lets to use other characters after the numbers - besides dots. Like a parenthesis / round bracket instead of a dot. Or handling of space between the number, punctuation mark and the content proper of list item.

CSS. Target Firefox only


CSS targeting Firefox web browser only: This text is red in Firefox HTML / XHTML. Code: <p>This text is red in Firefox</p> CSS. Code: @-moz-document url-prefix() {p {color: #f00;}} Unlike the method of styling elements for Opera browser only, it is essentially a hack - since the rule originally is intended for a different purpose. But lack of support in browsers other than Firefox allows to isolate code for use by Firefox web browser only. [ 1 ] Other browsers with Gecko web browser engine, like SeaMonkey 1.0+ or older Netscape 9.0, also support the hack. [ 2 ] Various versions of Internet Explorer, Google Chrome, Opera, Safari react to the hack as they are meant to - these browsers ignore the whole code of the Firefox specific hack. [ 3 ] There is also one more browser where text gets red - ELinks, an advanced text-based web browser with some support for CSS.

Unzip multiple files. Linux


Unzip multiple zip files into one directory by Linux command line unzip. Contrary to possible expectations, "unzip *.zip" is not going to work, *.zip should be put into quotes: unzip "*.zip" There may be files with the same names in these archives. To avoid overwriting: unzip -B "*.zip" "Unzip -B" makes unzip to overwrite duplicates during extraction process, but saving a backup copy of each overwritten file. The names for these backup copy files are created by adding tilde ("~") at the end of the original names of the files. If a file extension is present, then "~" is added after it. If that is not enough, unique sequence number (up to 5 digits) is appended after the "~". "Unzip -B" is not too practical. For example, since when the sequence number range for numbered backup files gets exhausted (99999, or 65535 for 16-bit systems), the backup file with the maximum sequence number is deleted and replaced by the new backup version without notice ( More on the subject ). The number of files in an archive may not be always known in advance or may be more than possible sequence number range, so "Unzip -B" is not a great choice. Renaming duplicate files by adding "~" at the end of their names, after the extension, is not too convenient either. But another built-in option is even worse. If the "-B" modifier is not used, each time a file with same name as there already unpacked is being extracted, unzip asks "replace example.txt? [y]es, [n]o, [A]ll, [N]one, [r]ename:". And each time "r" must be hit, then a new name has to be input. So some bash or another script solving the problem should probably be prepared and used instead.
