CSS horizontal centering of an image. Example:

Image

HTML / XHTML. Code:

<div class="example">

<img src="image.jpg" alt="Image" />

</div>

CSS. Code:

.example {position: relative; left: 0px; top: 0px; height: auto; width: 100%; float: left; padding: 10px; border: 1px #ccc solid; background: #fafafa;}

.example img {display: block; margin: 0 auto;}

CSS properties of a container (here it is example) may vary, image centering is achieved by styles applied to the image itself: .example img {display: block; margin: 0 auto;}.

HTTP to HTTPS redirect in .htaccess

 

Redirecting from all domain names of a web site to its web address with HTTPS and the domain with www. The names to be redirected from are: Both with and without www - URL with HTTP Without www - URL with HTTPS Server configuration: Apache + nginx. SSL is enabled. SSL-certificate is purchased, approved and installed. That is, everything is up and running. So it is just the HTTP to HTTPS redirection that is left to get ready and start up. Directives for .htaccess file: RewriteEngine On RewriteCond %{HTTP:HTTPS} !on [NV] RewriteRule ^(.*)$ https://www.domain.tld/$1 [R=301,L] RewriteCond %{HTTP_HOST} !^www\. RewriteRule ^(.*)$ https://www.domain.tld/$1 [R=301,L] HTTP to HTTPS redirect in detail -- Enable runtime rewriting engine: RewriteEngine On -- If HTTPS is not present: RewriteCond %{HTTP:HTTPS} !on [NV] -- Then replace HTTP + domain (with or without www) with HTTPS + domain with www: RewriteRule ^(.*)$ https://www.domain.tld/$1 [R=301,L] -- If HTTPS is present, but domain name has no www (the case when https://domain.tld is entered in address bar): RewriteCond %{HTTP_HOST} !^www\. -- Then replace it with HTTPS + domain with www: RewriteRule ^(.*)$ https://www.domain.tld/$1 [R=301,L] Notes RewriteCond %{HTTP:HTTPS} !on [NV] is not the only way to detect if HTTPS is not 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 not on. So it should probably be checked by practice what is going to work in a particular case. Apache Module mod_rewrite docs: http://httpd.apache.org/docs/current/mod/mod_rewrite.html
