Web authoring and site management

My Introduction to HTML also includes links to further information and style guides.
My Beyond HTML page contains information on style sheets, XML, JavaScript, the Semantic Web, etc.
My Language page includes links related to typography and fonts, including my page on the STIX fonts and my variant MASTIC (with small caps and a curvy lower-case italic v); and my page on the display of symbols in HTML.

Tools for HTML syntax & link checking

Here are a few of the many tools available.


Cascading Style Sheets are used to specify the appearance of Web pages. Current version is CSS 2.

CSS support across browsers is not entirely consistent (e.g., Mozilla CSS Reference and CSS Extensions).

CSS does not provide variables or macros. Various preprocessors have been created for this purpose, for example, Jon Gilkison's variables-in-css-via-php/ and Pete Boere's CSS Crush. (This selection is not based on my personal experience.)

See the interactive demo of advanced CSS features by Paul Irish, Jonathan Neal et al.

There are a great many tools available that are designed to make the use of CSS easier, such as Less and Sass. Frameworks based on Sass include Compass, Susy (designed to work with Compass), Bourbon, etc. I have no experience with any of these.

display:run-in was moved (2011 Jan) from CSS2 to CSS3 (ref, ref). It is in CSS3. As of 2014 Oct 31 it is labelled as experimental in Firefox (ref).


One way to create MathML, for inclusion in a Web page, is to use OpenOffice/LibreOffice. Use the formula editor in Writer, then export the document as XHTML. Extract the <math …> … </math> content from the XHTML file and paste it into the source for your Web page. It may be desirable to replace some special characters by the equivalent HTML entities (e.g., &sum; or &alpha;). It may also be desirable to use MathJAX by adding the following code to the page:

<style type="text/css">
/* don't use MathJax_Main because it doesn't have many accented characters */
  body { font-family: STIXGeneral, Mastic, serif }

<script type="text/javascript"
You may not really want to specify my Mastic font.

The use of MathJax improves the math rendering and also gives access to a TeX-like syntax for specifying math, which is especially useful for small bits where MathML is overkill. For example, \‍(w_i(\mathbf{x}), i=1,2,...n\) gives the in-line math \(w_i(\mathbf{x}), i=1,2,...n\), while \‍[w_i(\mathbf{x}), i=1,2,...n\] (with square brackets rather than parentheses) gives ‘displayed’ math: \[w_i(\mathbf{x}), i=1,2,...n .\]


OpenID is a mechanism for logging in to Web sites using ‘identities’ that have already been established on other sites. For example, suppose that site A provides OpenID's and site B accepts OpenID's. If someone has an account on site A, and has done whatever is required to establish an OpenID there (e.g., set up a profile), then they will be able to authenticate using that profile when logging in to site B, rather than having to create a new identity by registering at site B. It's quite easy to set up a site to accept OpenID's. Many organizations provide OpenID's. It's apparently not terribly difficult to become an OpenID provider, although I'm not clear about how trust is established.

There are somewhat confusing relationships among the OpenID Foundation, the Open Identity Exchange (OIX) and the National Strategy for Trusted Identities in Cyberspace (NSTIC) of the U.S.A. government.

Log analysis and server monitoring

Programmes for server-log analysis that are packaged in Debian include:

There are also real-time systems for analyzing site usage. An open-source alternative to Google Analytics is Piwik. It uses PHP and MySQL. It requires that some special JavaScript code be added to every page.


LAMP stands for Linux Apache Mysql PHP/Python/Perl.

Note that, under Debian, apache2 has two main flavours:

For MySQL, install mysql-client, mysql-server and php5-mysql.

HTML editors

This is a list of tools that seem to be (or used to be) popular, but I use Emacs myself. See also Wikipedia’s Comparison of HTML editors.


Old stuff

This list was compiled 1998–2000. Obsolete links have been updated or commented out; no new links have been added.
