CSS. Target Opera only

Windows : Opera 9.5+ [ 1 ] [ 2 ].

Linux : Opera 9.5+ [ 3 ].

CSS targeting Opera web browser only:

This text is red in Opera

HTML / XHTML. Code:

<p>This text is red in Opera</p>

CSS. Code:

doesnotexist:-o-prefocus, p {color: #f00;}

The -o-prefocus pseudo-class allows styling elements for Opera browser only. The code is placed in the common CSS file, not in a separate one as it is in case of Internet Explorer conditional comments.

[ 1 ]

Opera 3.5 - 5.0 ignores "doesnotexist:-o-prefocus" and reads code as p {color: #f00;}. Opera 6.0 - 9.4 ignores the whole code starting "doesnotexist".

[ 2 ]

Internet Explorer 5.5+, Firefox 1.0+, Google Chrome, Safari 3.1+, SeaMonkey 1.0+, Netscape 7.2+, Mozilla 1.5+ ignore the whole code starting "doesnotexist".

Older browsers like Internet Explorer before 5.5 or Netscape before 7.2 or Mozilla before 1.5 seem to ignore the uncommon, Opera 9.5+ specific code ("doesnotexist:-o-prefocus") and apply styles to what they understand - here it is the p tag; making the text in it red.

The text is red in Dillo 3.0.1 as well.

Internet Explorer 3

 

Features : Screenshots : Download links World Wide Web service with its online experience like hypertext links, surfing, web pages as a combination of text and images / multimedia brought Internet to general public. As to general public, it all very much revolves around the web browser. The first web browser ever, WorldWideWeb (later renamed Nexus) had many of the features later to be considered as standard for web browsers, but it was an experiment, accessible and known to very few. The rest of users might expect more likely only a text-mode interface experience through a text-based web browsers like Line Mode Browser. The turning point for the World Wide Web and all Internet was the advent of Mosaic, a graphical web browser, in 1993. First for Unix and then for Apple Macintosh and Microsoft Windows. Mosaic was not the first web browser for Windows though and it could not supersede Cello, the first and initially the only web browser for Windows. Microsoft Windows was the fastest growing major platform for PC in the first half of 1990s. But Microsoft did not seem to recognize the importance of the web browser then. So the main competition under Windows at that time was among several versions of Mosaic and Cello. This competition gave birth to Netscape web browser, which became the dominant software of its kind for several years. This success and great public attention attracted by World Wide Web by 1995 made Microsoft to join in the efforts. Internet Explorer 1 was just a first experiment. Internet Explorer 2 was intended to push the Internet Explorer case - it was made available to all Windows users for free, even commercial companies. But Netscape positions were not much undermined, Internet Explorer 2 being distinctly weaker in many features is among the reasons for that. Only after the release of Internet Explorer 3.0 Microsoft browsers began to close Netscape in qualities. Internet Explorer 3 was not the first Microsoft attempt to find technical and marketing model like were Internet Explorers of 1 and 2. And it was not the first Microsoft modern web browser, the first for Microsoft to beat and surpass Netscape and all other web browser competitors like Internet Explorer 4 was. But Internet Explorer 3 still was the first in some things: the first commercial browser with Cascading Style Sheets / CSS support, the first Microsoft web browser without Spyglass source code and the first Microsoft web browser to gain a significant user share, 20-39% by the end of 1997 [ 1 ]. Still, Internet Explorer 3 was a transitional, intermediate piece of software between the early browsers and the modern ones. As to its modern state, there is an interesting detail: Internet Explorer 3 can run under 32-bit Windows 7, unlike generally the 4.0-6.0 Explorers. Features HTML (with tables and frames) support is quite strong ( More ), Internet Explorer 3 lets some HTML tricks to be used without extra strain, like "HTML table borders without CSS". CSS support in Internet Explorer 3 is weak ( More 1 ) ( More 2 ). Internet Explorer 3 also supports VBScript, ActiveX (more than 1,000 Controls), Java applets, inline multimedia, VRML and a Microsoft's reverse-engineered version of JavaScript named JScript. All of the versions and capabilities corresponding to the level of the times. Internet Explorer 3 was released for several platforms: x86(16/32 bit), 68k, PPC, MIPS, Alpha AXP. And several operating systems: Windows 3.1, Windows 95, Windows NT, System 7 / Mac OS 7, Mac OS 8.

ELinks. Configuration

 

Jump to: ELinks - Text-based or console web browser. Description: features, screenshots, download links. ELinks. Use - How to use ELinks. What ELinks can and what can not, i.e. what may be configured depends on several things. The most common are capability of the console it is run on and support of what was chosen during the compilation process of an ELinks browser source code. Under certain operating systems (Windows for instance) it is easier and more reliable to omit some possible features. The configuration of ELinks 0.12pre2 from Package Database of Zenwalk Linux (originally based on Slackware, still keeping compatibility with its binary packages) is discussed here. It is quite representative in its qualities among other Linux ELinks browser versions for desktop PC computers. User interface of Windows ELinks and that of Linux / some other *nix systems ELinks of comparable versions are the same. If an ELinks package has been compiled without some feature or the console is not capable of something then it just will not be possible to choose the feature in the configuration process; or possible, but it will not work. For example, if this ELinks is compiled without support of 256 colors or your console is not capable of displaying them, then it just will only be possible to choose 16 or "No colors (mono)" in the menu. And the ELinks will work as much well in the rest. The whole configuration of ELinks may be done through the menu of the browser - there is no need to edit config files. Even if some fine-tuning may require editing of elinks.conf or even source code files - but that is not the issue for average use. The menu of ELinks is hidden when it is displaying a web page: To access the menu, press Esc on the keyboard: Configuration options are in "Setup" group: 1 ) "Language" - set a language of ELinks user interface. It is possible to set it to the system language or to several others. System and terminal emulator / console have to be prepared for this change - corresponding localization / internationalization files installed and configured. Choose a language (English in this example): To keep it, press Esc again, then Setup, then Save options, then confirm by clicking OK.
