Include another file
- Using server-side include
- If it doesn't work, TRY NAMING THE FILE WITH A .shtml EXTENSION!
- In Apache, SSI (include module) must be enabled.
<!--#include file="insertthisfile.html" -->
<!--#include virtual="insertthisurl_cgi.html" -->
- Using server-side include - PHP
- We can also use PHP, if the server is configured for it:
<?php include("filename.html"); ?>
<?php include("http://www.othersite.com/filename.html"); ?>
Tips and Pits
Set charset specification in the first 1024 bytes
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />in HEAD tag must come soon enough.
The page was reloaded, because the character encoding declaration of the HTML document was not found when prescanning the first 1024 bytes of the file. The encoding declaration needs to be moved to be within the first 1024 bytes of the file.
Set multi-column layout, with no-break sections
- See This SO.
- We can use
break-inside: avoid-column;on all browsers but FF, anddisplay: tablein FF 20+ - For instance, to prevent breaks in bulleted list.
.x {
-moz-column-count: 3;
-webkit-column-count: 3;
column-count: 3;
width: 30em;
}
.x ul {
margin: 0;
page-break-inside: avoid; /* Theoretically FF 20+ */
break-inside: avoid-column; /* Chrome, Safari, IE 11 */
display:table; /* Actually FF 20+ */
}
Table: Use same width for all columns except first one
Tricks: use min-width for the first column, and allocate 100% width to the remaining columns.
{| class="wikitable" width="100%"
|-
| style="min-width: 6em;" | First
| width="50%" | Second
| width="50%" | Third
|-
| Foo
| Bar
| Baz
|}
| First | Second | Third |
| Foo | Bar | Baz |
Format HTML
Using tidy:
# tidy is an terrible spammer, make sure you mute the warnings explicitly (as if --quiet was not enough)
tidy -q -i -m -w 160 --show-warnings no -ashtml -utf8 replay.html
