CSS centering <hr />

Windows : Internet Explorer 4.01 and 8.0+, Firefox 1.0+, Google Chrome, Opera 3.5 - 4.0 and 7.0+, Safari 3.1+, SeaMonkey 1.0+ [ 1 ].

Linux : Firefox 1.0+, Google Chrome / Chromium, Opera 7.0+, SeaMonkey 1.0+ [ 2 ], NetSurf 3.0+, Hv3.

CSS centering <hr />, if its width is less than 100%. Horizontal centering. Example:


HTML / XHTML. Code:

<hr />

CSS. Code:

hr {width: 50%; margin: 0 25% 0 25%;}

/* Extra CSS, just styling the look: */

hr {height: 1px; float: left; border: 0px; color: #f00; background: #f00;}

Note: mostly it works both with float: left and float: none. But float: left makes it for sure.

HTTPS to HTTP redirect for a single page

 

Redirecting a single page with HTTPS to the page with HTTP. Server configuration: Apache + nginx. SSL is enabled for the whole web site, so all pages are served with HTTPS. But there is a need to make just one single page to be with HTTP. Directives for .htaccess file: RewriteEngine On RewriteCond %{HTTP:HTTPS} on [NV] RewriteRule ^(page\.html)$ http://%{HTTP_HOST}/$1 [R=301,L,QSA] HTTPS to HTTP redirect for a single page in detail -- Enable runtime rewriting engine RewriteEngine On -- If HTTPS is present RewriteCond %{HTTP:HTTPS} on [NV] -- Then, when a page name and extension correspond to the search group in parentheses, form for it a URI with HTTP RewriteRule ^(page\.html)$ http://%{HTTP_HOST}/$1 [R=301,L,QSA] Notes RewriteCond %{HTTP:HTTPS} on [NV] is not the only way to detect if HTTPS is present. Moreover, for some server configurations other directives may be more suitable, like RewriteCond %{SERVER_PORT} 443 for example. The point is to find out somehow if HTTPS is on. So it should probably be checked by practice what is going to work in a particular case. QSA is used to keep the existing query string, if there is any, when the replacement URI also contains a query string. So that in the end both query strings are to be combined.
