- Labels
- Labels are the names and terms used throughout a website that identify
menu options, site categories or other elements.
- Label
Element
- The label element associates a label with a form control
- Layout
Table
- 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.
- Language
Attribute
- 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. For example:
<html lang="en-us">
The "en-us" means English as spoken and written in the
United States. Identifying language helps a user agent to
display text appropriately for that language. For example,
IBM Home Page Reader knows a few languages, and if the
language is not indicated in the document using the lang
attribute, then it applies the rules of whatever language
has been selected the default in its settings.
If language changes inside a document it should also be
indicated, since the user cannot (in practice) modify the
settings on the fly in the middle of a document. Thus, if
you have French words or phrases in a document, you should
use lang markup for them, e.g.
<span lang="fr">Loire</span>
.
- Leading
- 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
- Legibility indicates how clear text is visually.
- Likert Scale
- A likert scale is a type of question where respondents
are asked to rate the level at which they agree or disagree
with a statement. For instance on a scale from one to five
a user can strongly disagree or strongly agree with a
statement.
- Line-box
- 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.
- Line-height
- 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.
- Lines Per Inch
- Lines Per Inch is a vertical measure of density but
it's not worth worrying about. If you're have your Dots Per
Inch high enough then you won't have Lines Per Inch
problems and you don't have to bother with it. It refers to
the frequency of horizontal and vertical lines on a
halftone screen. I think photoshop occasionally brings up
the subject of LPI just to make sure amateurs continue to
find it impenetrable. When you come across the term, think
of lpi as around half or two thirds of Dots per inch and
you won't go far wrong.
- Linearized Table
- 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
- Link rot is the degeneration of a web page due to the links that become
invalid.
- Link
Element
- The link element defines the relationship between two
linked documents. It goes in the head section, but it can
appear repeatedly.
- Liquid Design
- A liquid designed web page re-scales to fit different resolutions
and different window sizes.
- Local
Navigation
- Local navigation is a type of navigation where choices
lead to subtopics defined by one of the main menu
subjects.
- Logical
Operators
- 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.
- Longdesc
- 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
- Look and feel is the visual appearance that identifies
a web site. It is comprised of a consistent color scheme,
layout, typography, design treatments and graphic elements
- all of which should work in harmony.
- Lorem Ipsum
- 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.
- Low
Vision
- The term used to describe a person who is without a
significant measure of vision but is not totally
blind.
- Lynx
- A text only browser that is popular in amongst UNIX
users, and commonly used by people with disabilities and
those in low bandwidth areas. It can be downloaded from the Lynx site.
