Explanation:
CSS is a style sheet language which stands for Cascading Style Sheet.
Explanation:
HTML element h1 is used in CSS for styling then it is also called a selector. Attributes are the special words which
control the element’s behaviour. To show the start and end of HTML element, tag is used.
Explanation:
tag is used to embed CSS in HTML page, while is used to embed JS in HTML.
is HTML5 declaration.
Explanation:
CSS is a style sheet language which stands for Cascading Style Sheet. CSS has introduced text, list, box,
margin, border, color, and background properties.
Explanation:
For binding a particular unique element, id selectors are used. While for group of elements,
class selector can be used.
Explanation:
Blurs an element, for use by the filter property. Accepts a distance measurement within which
pixels are randomly scattered. A value of 0 leaves the image as is.
Explanation:
A value of 100% or decimal value of 1 leaves the image as is, while 0 produces black. Increasing the value from
1 or 100% brightens pixels from their original values.
Explanation:
A value of 100% or a decimal value of 1 leaves the image as is, while 0 results in black. Increasing the value
past 1 or 100% produces more dramatically stratified areas of light and dark
Explanation:
A decimal value between 0 and 1 or percentage up to 100% controls the extent of the color-negative effect,
with 0.5 or 50% producing gray.
Explanation:
A decimal value of 1 or percentage of 100% keeps the image as is, while increasing the amount produces
more dramatically stratified hues.
Explanation:
Browser sometimes adds prefixes to non-standard CSS properties. CSS Extension prefix for Webkit is -webkit
which is supported by almost all ios browsers. -o is used by opera where as -moz is used by firefox browser.
Explanation:
The attribute in html aligns the text in center. In CSS, this is equivalent to align property which can
align text to right, left or center as per the value. Margin property sets the margin for an element. Color property is used to
set/assign colour to element. Font property is for increasing/decreasing the font of text.
Explanation:
Both font-style and font-family are for styling the text. They show text in different kinds of styles. Color is for
setting/assigning colour to text or element. The font-size property in CSS is equivalent to attribute . Both of them
either increase/decrease the font of text.
Explanation:
Text-decoration is a CSS property used to decorate the text. The text-decoration property takes many values
such as overline, underline, line-through, none, inherit, etc. Overline gives a line over the text. Underline value is used to add
line under the text. None value defines a normal text. When one wants to give a line through the text, line-through value for
text-property can be used.
Explanation:
CSS level 2 revision 1, often referred to as “CSS 2.1”, fixes errors in CSS 2, removes poorly supported or not fully
interoperable features and adds already implemented browser extensions to the specification. To comply with the W3C Process
for standardizing technical specifications, CSS 2.1 went back and forth between Working Draft status and Candidate Recommendation
status for many years. CSS 2.1 first became a Candidate Recommendation on February 25, 2004, but it was reverted to a Working Draft
on June 13, 2005 for further review.
Explanation:
CSS 2.1 has a grammar (www.w3.org/TR/CSS21/grammar.html) but unlike traditional (X)HTML it is not defined
with a document type definition. Instead the CSS specification is a combination of prose and a grammar that could be used to
build a simple parser.
Explanation:
Align is used to align the content either left, right or center. Ruby describes CSS properties to manipulate the
position of “ruby”, which are small annotations on top of or next to words, especially common in Chinese and Japanese.
They are often used to give the pronunciation or meaning of difficult ideograms. Text-align is for aligning the text either
left, right or in center.
Explanation:
In inline style, properties are confined with a particular element to which it is applied. It won’t be applied to
other element of the same type. We need to reapply style information throughout the document whenever it is necessary.
Explanation:
Linked information regarding CSS like external CSS document information is always placed in
tag. tag contains the body of the document.
Explanation:
Defines a measurement relative to the height of a font in em spaces. Because an em unit is equivalent to the size
of a given font, if you assign a font to 12pt, each em unit would be 12pt, thus 2em would be 24pt.
Explanation:
Defines a measurement as a percentage. Percentages are denoted by a number followed by the % symbol and
are always relative to another value such as length. Quite often they are used to specify some value relative to an inherited
value from a parent element.
Explanation:
An RGBa is specified via a function style rgba(r,g,b,a) value, where colors r, g, and b are specified as a decimal
value from 0 to 255 or a percentage from 0 to 100%, and the alpha channel value for defining opacity is a number between
0 (fully transparent) and 1 (fully opaque). Values outside this range will be rounded up or down to fit the closest value.
Explanation:
maroon (#800000) red (#ff0000)
orange (#ffA500) yellow (#ffff00)
olive (#808000) purple (#800080)
fuchsia (#ff00ff ) white (#ffffff)
lime (#00ff00) green (#008000)
navy (#000080) blue (#0000ff)
aqua (#00ffff) teal (#008080)
black (#000000) silver (#c0c0c0)
gray (#808080)
Other color keywords may be commonly used but are ad hoc in their definition.
Explanation:
The format specifies color as #rrggbb, where rr is the amount of red, gg the amount of green, and bb
the amount of blue, all specified in a hexadecimal value ranging from 00 to FF.
Explanation:
RGB color values can also be defined using percentages. The format is the same, except that the numbers are
replaced by percentage values between 0% and 100%.
