Basic Css — Part 1 MCQs with Explanations

CSS stands for Cascading Style Sheets.

It is good pratice to inlcude H1 heading only once and to use H2-H6 heading in others areas.

The filter property in CSS is used to apply various visual effects to an element, such as blurring an image. To blur an image, the blur() function is used in the filter property. Therefore, the correct answer is option C, "blur()". Let's understand the other options: Option A, "opaque()", is not a valid function used with the filter property. It does not apply blurring effects. Option B, "scatter()", is also not a valid function used with the filter property. It does not apply blurring effects either. Option D, "all of the mentioned," is incorrect because options A and B are not valid functions used for blurring images with the filter property. Therefore, the correct answer is option C, "blur()", as it is the function used by the filter property to blur images.

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.

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.

A decimal value between 0 and 1 or percentage up to 100% controls the extent of the gray effect.

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.

A decimal value of 1 or percentage of 100% keeps the image as is, while increasing the amount produces more dramatically stratified hues.

Syntax: font: font-weight font-style font-variant font-size/line-height font-family .

Values for margin such as auto generally are used when centering blocks with textalign for content.

In the case of some elements such as <img> , the CSS float property is more appropriate than text-align .

The first CSS specification to become an official W3C Recommendation is CSS level 1, published on December 17, 1996. Håkon Wium Lie and Bert Bos are credited as the original developers.

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.

Here is no single, integrated CSS4 specification,[42] because it is split into separate modules. However, there are “level 4” modules.

Unlike CSS 2, which is a large single specification defining various features, CSS 3 is divided into several separate documents called “modules”. Each module adds new capabilities or extends features defined in CSS 2, preserving backward compatibility.

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.

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.

In this case, we should see the browser continue to parse the value of color as “red textdecoration: underline” before it sees a closing semicolon. The font-style property that follows would then be used. Because the color property has an illegal value, it should be ignored.

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.

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.

Syntax: font-size: length | percentage | larger | smaller | xx-small | x-small | small | medium | large | x-large | xx-larger | inherit

Syntax: font-variant: normal | small-caps | inherit

Syntax: list-style-type: disc | circle | square | decimal | decimal-leading-zero

Syntax: list-style-image: url(url of image) | none

Syntax: letter-spacing: length | normal | inherit

This is useful if you want to dynamically change one color and have other related colors change.

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.

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.

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.

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%.

em is a Relative Unit

Example: p {color:rgb(0%,10%,50%);}

href attribute specifies the URL of the linked resource. A URL might be absolute or relative.

Selector is the correct answer to “In css what does h1 can be called as”. This question is standard in competitive examination syllabi for Basic Css.

Declaration is the correct answer to “In css what does “color:red” can be called as”. This question is standard in competitive examination syllabi for Basic Css.

all of the mentioned is the correct answer to “Which of the following attributes is used to specify elements to bind style rules to”. This question is standard in competitive examination syllabi for Basic Css.

id is the correct answer to “________ selectors, which are used to specify a rule to bind to a particular unique element”. This question is standard in competitive examination syllabi for Basic Css.

Property-Name is the correct answer to “In css what does “font-size” can be called as”. This question is standard in competitive examination syllabi for Basic Css.

class is the correct answer to “_________ selectors, which are used to specify a group of elements”. This question is standard in competitive examination syllabi for Basic Css.

css is the correct answer to “__________ implementation that introduced text, list, box, margin, border, color, and background properties.”. This question is standard in competitive examination syllabi for Basic Css.
