I
- ID
Attributes and Selectors
- Document languages may contain attributes that
are declared to be of type ID. What makes attributes
of type ID special is that no two such attributes
can have the same value; whatever the document language,
an ID attribute can be used to uniquely identify
its element. In HTML all ID attributes are named "id";
XML applications may name ID attributes
differently, but the same restriction applies.The
ID attribute of a document language allows authors
to assign an identifier to one element instance
in the document tree. CSS ID selectors match an element instance
based on its identifier. A CSS ID selector contains a "#" immediately
followed by the ID value. ID selectors have a higher
precedence than attribute selectors. For example,
in HTML
, the selector #p123 is more specific than [ID=p123]
in terms of the cascade.
- If
Structure
- In programming, an if structure allows you to
execute select lines of code only when specified
conditions are true.
- If...else
Structure
- In programming, an if ...else structure executes
a statement based on the value of if. If the tested
condition returns false, PHP allows you to specify
another block of code to be executed using the else
keyword. Each of these conditionally executed blocks
of code is known as a branch, and each branch must
be placed within braces if it contains more than
one line of code.
- @import
rule
- In CSS,
the '@import' rule allows users to import style
rules from other style sheets. Any @import rules
must precede all rule sets in a style sheet. The
'@import' keyword must be followed by the URI of
the style sheet to include. A string is also allowed;
it will be interpreted as if it had url(...) around
it.
- Inclusive
Design
- Inclusive design means developing systems or web
sites flexible enough to serve the broadest possible
range of users. Inclusive design calls for adaptable
interfaces to be built into the product early in
the design phase, producing features easily used
by everyone. It allows for customization based on
user preference. It provides equivalent access to
content (e.g. auditory and visual) based on user
preference. Inclusive design provides access to
users with disabilities and provides better usability
for everyone.
- Image
Map
- Areas of an image on a web page that have links
to other areas of the Web. Some types of images
map can have alt tags on the areas, while others
must have text links.
- Inline
Element
- Inline (also known as "text level") elements typically
contain text and other inline elements. When rendered
visually, inline elements do not usually begin on
a new line. Inline content is displayed with no
line breaks before and afterwards. Examples of inline
elements include emphasised text, strong text and
links.
- Inline
Style Sheet
- An inline style controls the appearance of a single
element. CSS rule(s) are placed in the HTML via
the style attribute. With inline, style and content
are intermingled in the body of the document.
- Information
and Communications Technology (ICT)
- A generic name for all of the technologies involved
with communicating with computers.
- Information Architect
- A person who organizes inherent patterns in data
to make complexities clear. He or she uncovers patterns
and relationships and then structures content allowing
users to find paths to knowledge.
- Information
Architecture
- Information architecture is the organization of
information. This field studies how to organize
information most effectively to help people find
and use the information. It also refers to the structure
or organization of a website, especially how pages
relate to one another.
- Inline
Box
- In CSS,
the inline box is the addition of (half-)leading
to the content-area for each element. For for replaced
elements height of the inline box of an element
will be exactly equal to the intrinsic height of
the element plus any margins, borders, or padding.
For non-replaced elements height of the inline box
of a non-replaced element will be exactly equal
to the value for line-height.
- Inquiry
- Inquiry is a broad category of usability evaluation
methods. It is part one of the "Usability Evaluation
Toolbox". With inquiry methods usability evaluators
obtain information about users' likes, dislikes,
needs, and understanding of the system by talking
to them, observing them using the system in real
work (not for the purpose of usability testing),
or letting them answer questions verbally or in
written form. Numerous methods exist for doing inquiries.
- Inheritance
- A mechanism in CSS by which some values are passed down
to the children of an element in the document tree.
Each property defines whether it is inherited or
not. It is the mechanism by which styles applied
to an element are assumed by any descendant elements.
- Inspection
- Inspection is a broad category of usability evaluation
methods. It is part two of the "Usability Evaluation
Toolbox". In the inspection approach, usability
specialists, users and other professionals examine
usability related aspects of a user interface. Numerous
methods exist for doing inquiries.
- Inverted Pyramid
- The inverted pyramid is a type of writing style
where conclusions are presented first not last.
It begins with a conclusion then moves to the key
information followed by background information.
Usability studies show that web users want instant
gratification. That is why the inverted pyramid
style is important.
- Iterative
Design
- Iterative design is a process where a web site
progressively develops in a repeated cycle. Iteration
is repeated revisions.
