Aliasing
In graphic design terminology, aliasing is the situation where a graphic image is expanded larger than its original resolution, or if a monitor or printer does not have a high enough resolution, its edges start to get jagged.

Alignment
The positioning of text or an image on a web page. Professional web designers use tables and/or Cascading Style Sheets to align elements on a web page.

Alt attribute
The HTML "alt" attribute provides alternative text for graphic images. Used to help Internet users on modems or on limited bandwidth Internet connections load web pages quickly without downloading the graphics and know what the graphic's content is. Screen-reader users, language translation applications and some hand-held devices that do not access or download images also use the alt data. AKA "alt tag".

Alt Text
Alt text is the word, phrase or sentence contained within the quote marks of the alt attribute and seen by a viewer when the mouse hovers over the image. The wrong or inadequate alt text can make your images inaccessible to people depending on the screen readers.

Alternate Style Sheet
A capacity of using Cascading Style Sheets is that web designs can allow website visitor to select an alternate style sheet, usually provided to allow switching to a larger font size.

Analytics

Flash is an alternative animation technology to animated GIFs. Flash slide show animation as well as videos. Flash animation requires a Flash Player freeware that plays the single file that contains multiple images.

Applet
A small Java application that is coded in a web page or stored in a file that the web page calls up. It cannot be run by itself.

Attribute
In HTML and XML, an attribute is a characteristic of an element, for example a paragraph may be defined by a style attribute. Attributes are largely getting replaced by style sheets external to the web page, such as Cascading Style Sheets.
