Web Development

Linux/Apache/MySQL/PHP; A popular Open Source Website platform combination of Operating System (Linux), Web server (Apache), database (MySQL) and scripting language (PHP).

Labels are the names and terms used throughout a Website that identify menu options, site categories or other elements.

An easy accessibility feature to add (and it is even AAA WCAG) is the language attribute lang="en-us" to the HTML tag to identify the primary natural language of a document.

A table that uses rows and columns to organize content visually on the screen. In a layout table, the positioning of content in particular cells does not imply a relationship to the content in other cells as it does in a data table.

The difference between the values of line-height and font-size. It is the extra space between the lines of text above and below the font's size.

Legibility indicates how clear text is visually.

In CSS, a line-box is the box which bounds the highest and lowest points of the inline boxes which are part of the line. It is the distance from the top of the highest inline box in the line to the bottom of the lowest inline box in the line. A line-box is as tall as the inline boxes within a line. That is, the top of the tallest inline box and the bottom of the lowest inline box define the top and bottom of the line box. That determines the separation between baselines.

This style sheet property determines the amount by which the height of each element's line box is increased or decreased. Basically it is not a set measurement, but a calculation. In CSS, line-height is the difference between the values of line-height and font-size for a given element. The line-height property specifies the logical height of an inline element. This is the height used in the vertical alignment of inline elements and the construction of line boxes. It defines the height of the inline box for a given element. It determines the amount by which the height of each element's linebox is increased or decreased.

A table rendering process where the contents of the cells become a series of paragraphs (e.g., down the page) one after another. The paragraphs will occur in the same order as the cells are defined in the document source.

Link rot is the degeneration of a Web page due to the links that becomes invalid.

Search engines often use link popularity as part of their ranking criterion. In simple terms, link popularity is the measurement of the number of other Web sites that include a link to your Web site on theirs. Each search engine, depending on their specific algorithms, determines it differently.

An Open Source computing platform based on the robust core of commercial Unix systems. Developed by a Norwegian programmer named Linus Torvald in the early 90's, the Linux core is available in dozens of popular distributions (or 'flavors') such as the popular RedHat, Mandrake, Slackware and Debian. Linux is become popular because it is free, flexible and secure.

A liquid designed Web page re-scales to fit different resolutions and different window sizes.

Text that is categorized, be it bulleted, numbered, or unnumbered. The default list bullets and numbers are black with no special effects. To make a bulleted list using graphic images as bullets, Web graphic designers use a table format.

Local navigation is a type of navigation where choices lead to subtopics defined by one of the main menu subjects.

"localhost" is an alias for the address 127.0.0.1, an address that always indicates the local computer. This is the address that a computer can use to refer to itself. For example, when testing a Web application on the same computer as the server, you can use the address http://127.0.0.1 or http://localhost

In programming, logical operators are used to combine conditions, so that multiple conditions can be evaluated together as a single expression. For instance, they allow a script to determine the status of conditions and in the context of if...else or while statements and execute code based on which conditions are true or false.

Similar to alt text, the longdesc associates an image description with the code that places the image in the page. This is in contrast to the D link, which simply places a link near the image.

Look and feel is the visual appearance that identifies a Website. It is comprised of a consistent color scheme, layout, typography, design treatments and graphic elements - all of which should work in harmony.

Lorem Ipsum or Lipsum is random text. It is a common piece of garble that designers use as mock-content when testing layouts. It has been well established that if you write anything in a sample layout or design, people will spend more time reading the copy than looking at the full concept. "Lorem ipsum dolor" is sufficiently like ordinary text to show "text goes here" but it doesn't distract the reader.
