HTML table borders without CSS

Some time ago, mostly (but not only) in 1990s there were several pure HTML tricks used to achieve things now done by CSS. Handling HTML table borders was one of them.

It is not exactly handling borders, but rather imitating doing it by exploiting the cellspacing and bgcolor attributes. Nowadays, as with centering page content by table tag, this method is perfectly usable, even if obsolescent in its concept.

The concept

1. The bgcolor attribute of the table tag is used to make the background of a table to be of a certain color.

2. The bgcolor attribute of the tr tag is employed to make the background of the table's content (i.e., rows and cells) to be of a certain, different from the table's background, color.

3. The cellspacing attribute of the table tag is used to create the space of a certain amount of pixels around the table cells. That space gets the color set by the bgcolor attribute of the table tag - since it differs from the background of rows and cells, this creates visual boundary line of the table's background color around the cells.

The steps aforementioned create in Arachne a visual boundary line only between the table cells, not around them. And these steps does not make at all any visual boundary line in Netscape 3.04-6.0 and Mozilla 0.6-0.92. So an additional table around the first one should be created.

The bgcolor attribute of the table tag is removed from the inner table and given to the outer one. The cellspacing attribute of the outer table is set to "0". It creates the required visual boundary both in Arachne and Netscape 3.04-6.0, Mozilla 0.6-0.92.

This method works not only in Netscape 3.04-6.0, Mozilla 0.6-0.92 and Arachne, but also in other web browsers as well, so it may be used as a universal one.

It works also in Opera 2.12 - 3.50, but with certain flaws.

Dillo - partially. Dillo does not recognize the height attribute for td or tr. The visual boundary line trick in itself does work.

With a minor flaw.

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.

Arachne. Graphical web browser for DOS

 

Jump to: Arachne web browser. Installing and setting up for internet connection via Ethernet Arachne web browser. Installing and setting up for dial-up internet connection Versions : Configuration and use : Download links Arachne is a full-screen graphical web browser for DOS on PC computers. Originally developed by Michael Polák. First release - 22th December 1996. The last Arachne version by Arachne Labs was released on 22th January 2001. Arachne source code was opened in November of 2003 and the subsequent versions are released under GNU GPL license. Arachne is distributed as a software suite containing, besides web browser, built-in e-mail client, FTP, internet connection wizard, WAV files player. More add-ons are available: image viewer, PDF, file managers, mplayer, Telnet client, IRC and more. Arachne supports Windows-1251 and KOI8-R Cyrillic after additional packages are installed. Internet connection is via serial ports (COM) and Ethernet. There are also Arachne for Linux / SVGAlib. Versions GPL versions of Arachne. The main line of Arachne development. Major changes and updates take place within its framework. Maintained by a group of enthusiasts who also develop GPL version for Linux / SVGAlib. Arachne Labs versions. Arachne Labs, xChaos software initially, were the main structure engaged in development of Arachne until 2003, when Arachne source code was opened and the GPL versions of the browser became the main line. The last Arachne Labs version was released on 22th January 2001: Arachne 1.70 Release 3. Ray Andrews version. A GPL Arachne variation. PTS-DOS version. Similar to the corresponding versions of Arachne, but to some extent integrated with the PTS-DOS distribution. DR-WebSpyder. Based on Arachne. Basically - different web browser, for which Arachne is just an ancestor. Later the browser was renamed as Lineo EmBrowser. Configuration and use Arachne web browser was created in DOS and for DOS (the Linux version stands somewhat apart). Therefore, even though Arachne will run under many versions of Windows, Windows XP for instance, it is working under DOS when Arachne qualities are revealed best. Arachne web browser works in all major DOS variants, for example MS-DOS, FreeDOS or PTS-DOS. System requirements are low. The minimum: 80x86 CPU, 500 KB DOS base memory, 1 MB XMS/EMS memory, 512 KB SVGA video, 5 MB HDD space. Although requirements for using maximum screen resolution, maximum color depth are higher. But in this case too they are extremely small by today's standards - 486, better Pentium I computer, 640 KB base memory, 8+ MB XMS/EMS memory, 2+ MB SVGA video. Yet it depends - using 640x480 screen resolution, installing Arachne on RAM disk let to have Arachne running quite well on 386 CPU computer; if only there are enough of RAM and video adapter capabilities. Besides traditional hard disk installation, DOS LIVE CD by Roman Karpach may be used ( www.fdd5-25.net/doslivecd ), where Arachne web browser is among the software present. The characteristics of Arachne web browser installation process make the main settings be set right from the beginning. These settings for the most part are the responsibility of operating system on computers running Windows, Mac OS X or Linux, but in DOS Arachne browser takes care of everything itself.
