What Is The Purpose Of % Measurement Unit?
% - Defines a measurement as a percentage relative to another value, typically an enclosing element.
p {font-size: 16pt; line-height: 125%;}
What Is The Purpose Of Cm Measurement Unit?
cm − Defines a measurement in centimeters.
div {margin-bottom: 2cm;}
What Is The Purpose Of Em Measurement Unit?
em − A relative measurement for 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.
p {letter-spacing: 7em;}
What Is The Purpose Of Ex Measurement Unit?
ex − This value defines a measurement relative to a font's x-height. The x-height is determined by the height of the font's lowercase letter.
p {font-size: 24pt; line-height: 3ex;}
What Are Advantages Of Using Css?
Following are the advantages of using CSS −
•CSS saves time − You can write CSS once and then reuse same sheet in multiple HTML pages. You can define a style for each HTML element and apply it to as many Web pages as you want.
•Pages load faster − If you are using CSS, you do not need to write HTML tag attributes every time. Just write one CSS rule of a tag and apply it to all the occurrences of that tag. So less code means faster download times.
•Easy maintenance − To make a global change, simply change the style, and all elements in all the web pages will be updated automatically.
•Superior styles to HTML − CSS has a much wider array of attributes than HTML, so you can give a far better look to your HTML page in comparison to HTML attributes.
•Multiple Device Compatibility − Style sheets allow content to be optimized for more than one type of device. By using the same HTML document, different versions of a website can be presented for handheld devices such as PDAs and cell phones or for printing.
•Global web standards − Now HTML attributes are being deprecated and it is being recommended to use CSS. So its a good idea to start using CSS in all the HTML pages to make them compatible to future browsers.
•Offline Browsing − CSS can store web applications locally with the help of an offline catche.Using of this, we can view offline websites.The cache also ensures faster loading and better overall performance of the website.
•Platform Independence − The Script offer consistent platform independence and can support latest browsers as well.

vmin 1vw or 1vh, whichever is smaller.
p { font-size: 2vmin;}
What Are Browser Safe Colors?
There is the list of 216 colors which are supposed to be most safe and computer independent colors. These colors vary from hexa code 000000 to FFFFFF. These colors are safe to use because they ensure that all computers would display the colors correctly when running a 256 color palette.
Which Property Is Used To Set The Background Color Of An Element?
The background-color property is used to set the background color of an element.
Which Property Is Used To Set The Color Of A Text?
The color property is used to set the color of a text.
Which Property Is Used To Set The Text Direction?
The direction property is used to set the text direction.
What Is Selector?
CSS selector is equivalent of HTML element(s). It is a string identifying to which element(s) the corresponding declaration(s) will apply and as such the link between the HTML document and the style sheet.
For example in P {text-indent: 10pt} the selector is P and is called type selector as it matches all instances of this element type in the document.
in P, UL {text-indent: 10pt} the selector is P and UL (see grouping); in .class {text-indent: 10pt} the selector is .class (see class selector).
What Is Css Rule At-rule ?
There are two types of CSS rules
ruleset and at-rule. At-rule is a rule that applies to the whole style sheet and not to a specific selector only (like in ruleset). They all begin with the @ symbol followed by a keyword made up of letters a-z, A-Z, digits 0-9, dashes and escaped characters, e.g. @import or @font-face.
As A Reader, How Can I Make My Browser Recognize My Own Style Sheet?

Internet Explorer 3.0 (Win95/NT)
[It is possible to do this at least in Windows95/NT, but no user interface is provided. Unknown how this might be accomplished on other operating systems.]
1. Open the Registry editor (Start..Run..regedit..ENTER)
2. Under the 'HKEY_LOCAL_MACHINESoftwareMicrosoftInternetExplorerStyles' key, Edit..New..String Value
3. The new value should be called 'StyleSheet Pathname'
4. For the value, type in the full directory path of your .css style sheet.

1. Under the View menu, select 'Internet Options'.
2. Under the 'General' tab, choose the 'Accessibility' button.
3. Choose the 'Format documents using my style sheet' check box and 'Browse...' to the location of your .css style sheet.
How Do I Design For Backward Compatibility Using Style Sheets?
Existing HTML style methods (such as <font SIZE> and <b>) may be easily combined with style sheet specification methods. Browsers that do not understand style sheets will use the older HTML formatting methods, and style sheetsspecifications can control the appearance of these elements in browsers that support CSS1.
Which Set Of Definitions, Html Attributes Or Css Properties, Take Precedence?
CSS properties take precedence over HTML attributes. If both are specified, HTML attributes will be displayed in browsers without CSS support but won't have any effect in browsers with CSS support.
What Are Inline, Block, Parent, Children, Replaced And Floating Elements?
Inline elements which do not have line breaks. Can occur in block elements or other inline elements, cannot contain block elements.

Parents and children elements which either contain (parents) or are in the content of (children) other elements, e.g. <P>text<STRONG>text</STRONG>text</P>. P is a parent of STRONG. STRONG is a child of P. If not specified otherwise, children will inherit parent's properties.
Replaced elements which content is replaced. For example content of the IMG element is replaced with an image, content of the INPUT element is replace with a field.
Floating
elements which follow the flow of a parent - inline elements.
What Is Embedded Style? How To Link?
Embedded style is the style attached to one specific document. The style information is specified as a content of the STYLE element inside the HEAD element and will apply to the entire document.
The Pack contains nearly 14 plus software . Pick the one which is suited for you Make your PC more useful. Get the free Google Pack.
<HEAD>
<STYLE TYPE="text/css">
<!--
P {text-indent: 10pt}
-->
</STYLE>
</HEAD>
Note: The styling rules are written as a HTML comment, that is, between <!-- and --> to hide the content in browsers without CSS support which would otherwise be displayed.
What Is Id Selector?
ID selector is an individually identified (named) selector to which a specific style is declared. Using the ID attribute the declared style can then be associated with one and only one HTML element per document as to differentiate it from all other elements. ID selectors are created by a character # followed by the selector's name. The name can contain characters a-z, A-Z, digits 0-9, period, hyphen, escaped characters, Unicode characters 161-255, as well as any Unicode characteras a numeric code, however, they cannot start with a dash or a digit.
#abc123 {color: red; background: black}
<P ID=abc123>This and only this element can be identified as abc123 </P>
How Do I Have A Fixed (non-scrolling) Background Image?
With CSS, you can use the background-attachment property. The backgroundattachment can be included in the shorthand background property, as in this example
body {
background: white url(example.gif) fixed ;
color: black ;
}
Note that this CSS is supported by Internet Explorer, Mozilla, Firefox Opera, Safari, and other browsers. In contrast, Microsoft's proprietary BGPROPERTIES attribute is supported only by Internet Explorer.
What Are Pseudo-classes?
Pseudo-classes are fictional element types that do not exist in HTML. In CSS1 there is only one element type which can be classed this way, namely the A element(anchor). By creating three fictional types of the A element individual style can be attached to each class. These three fictional element types are: A as unvisited link, A as active link and A as visited link. Pseudo-classes are created by a colon followed by pseudo-class's name. They can also be combined with normal classes
example
A:link {background: black; color: white}
A:active {background: black; color: red}
A:visited {background: transparent; color: black}
<A HREF....>This anchor (or rather these anchors) will be displayed as declared above</A>
A.foot:link {background: black; color: white}
A.foft:active {background; black: color: red}
A.foot:visited {background: transparent; color: black}
<A CLASS=foot HREF....>This anchor and all other anchors with CLASS foot will be displayed as declared above</A>
Can Style Sheets And Html Stylistic Elements Be Used In The Same Document?
Yes. Style Sheets will be ignored in browsers without CSS-support and HTML stylistic elements used.
Can Css Be Used With Other Than Html Documents?
Yes. CSS can be used with any ny structured document format. e.g. XML, however, the method of linking CSS with other document types has not been decided yet.
Some Examples Of Good And Bad Coding. What Is Wrong With This?
<font size="3">Welcome to my page</font>
Comment: The font-tag is design and design shouldn’t be in the HTML document. All design should be in the CSS-file! Instead do this
In the HTML
<h1>Welcome to my page</h1>
In the CSS
h1 { font-size: 2em; }
One more example
<b>An error occurred</b>
This looks right doesn’t it? But if you look up what <b> stands for you quickly find bold. But bold is certainly design, so it still doesn’t belong in the HTML document. A better choice is <em> that stands for emphasis or simply “this piece of text is important”. So instead of saying “this text looks like this” you are saying “this text is important” and you let the looks be decided by the CSS. Seems like a minor change, but it illustrates how to select your tags. Use this instead
In the HTML
<em>An error occured</em>
In the CSS
em {
font-weight: bold;
color: Red;
}
One last example
<table>
<tr><td><a href="">first link</a></td></tr>
<tr><td><a href="">second link</a></td></tr>
...
</table>
How To Use Css To Separate Content And Design?
The idea here is that all sites contain two major parts, the content: all your articles, text and photos and the design: rounded corners, colors and effects. Usually those two are made in different parts of a webpage’s lifetime. The design is determined at the beginning and then you start filling it with content and keep the design fixed.
In CSS you just add the nifty <link>-tag I’ve told you about to the head of yourHTML document and you have created a link to your design. In the HTML documentyou put content only, and that link of yours makes sure it looks right. You can also use the exact same link on many of your pages, giving them all of them the same design. You want to add content? Just write a plain HTML document and think about marking things up like “header” instead of “big blue header” and use CSS to make all headers look the way you want!
Why Was The Decision Made To Make Padding Apply Outside Of The Width Of A Box, Rather Than Inside, Which Would Seem To Make More Sense?
It makes sense in some situations, but not in others. For example, when a childelement is set to width: 100%, I don't think it should cover the padding of its parent. The box-sizing property in CSS3 addresses this issue. Ideally, the issue should have been addressed earlier, though.
Why Call The Subtended Angle A Pixel, Instead Of Something Else (e.g. Subangle)?
In most cases, a CSS pixel will be equal to a device pixel. But, as you point out, the definition of a CSS pixel will sometimes be different. For example, on a laser printer, one CSS pixel can be equal to 3x3 device pixels to avoid printing illegibly small text and images. I don't recall anyone ever proposing another name for it. Subangle? Personally, I think most people would prefer the pragmatic "px" to the non-intuitive "sa".
How Do I Eliminate The Blue Border Around Linked Images?
in your CSS, you can specify the border property for linked images
a img { border: none ; }
However, note that removing the border that indicates an image is a link makes it harder for users to distinguish quickly and easily which images on a web page are clickable.
Which Property Is Used To Change The Face Of A Font?
The font-family property is used to change the face of a font.
What Is A Style Sheet?
Style sheets are the way that standards-compliant Web designers define the layout, look-and-feel, and design of their pages. They are called Cascading Style Sheets or CSS. With style sheets, a designer can define many aspects of a Web page
* fonts
* colors
* layout
* positioning
* imagery
* accessibility
Style sheets give you a lot of power to define how your pages will look. And another great thing about them is that style sheets make it really easy to update your pages when you want to make a new design. Simply load in a new style sheet onto your pages and you're done.
What Is Inline Style? How To Link?
Inline style is the style attached to one specific element. The style is specified directly in the start tag as a value of the STYLE attribute and will apply exclusively to this specific element occurrence.
<P STYLE="text-indent: 10pt">Indented paragraph</P>
Why Do Style Sheets Exist?
SGML (of which HTML is a derivative) was meant to be a device-independent method for conveying a document's structural and semantic content (its meaning.) It was never meant to convey physical formatting information. HTML has crossed this line and now contains many elements and attributes which specify visual style and formatting information. One of the main reasons for style sheets is to stop the creation of new HTML physical formatting constructs and once again separate style information from document content.
What Are Style Sheets?
Style Sheets are templates, very similar to templates in desktop publishing applications, containing a collection of rules declared to various selectors(elements).
What Is Css Rule Ruleset?
There are two types of CSS rules: ruleset and at-rule. Ruleset identifies selector orselectors and declares style which is to be attached to that selector or selectors. For example P {text-indent: 10pt} is a CSS rule. CSS rulesets consist of two parts:selector, e.g. P and declaration,
e.g. {text-indent: 10pt}.
P {text-indent: 10pt} - CSS rule (ruleset)
{text-indent: 10pt} - CSS declaration
text-indent - CSS property
10pt - CSS value.
Which Property Is Used To Set The Background Image Of An Element?
The background-image property is used to set the background image of an element.
Which Property Is Used To Control The Repetition Of An Image In The Background?
The background-repeat property is used to control the repetition of an image in the background.
Which Property Is Used As Shorthand To Specify A Number Of Other Font Properties?
The font property is used as shorthand to specify a number of other font properties.
% - Defines a measurement as a percentage relative to another value, typically an enclosing element.
p {font-size: 16pt; line-height: 125%;}
What Is The Purpose Of Cm Measurement Unit?
cm − Defines a measurement in centimeters.
div {margin-bottom: 2cm;}
What Is The Purpose Of Em Measurement Unit?
em − A relative measurement for 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.
p {letter-spacing: 7em;}
What Is The Purpose Of Ex Measurement Unit?
ex − This value defines a measurement relative to a font's x-height. The x-height is determined by the height of the font's lowercase letter.
p {font-size: 24pt; line-height: 3ex;}

•Global web standards − Now HTML attributes are being deprecated and it is being recommended to use CSS. So its a good idea to start using CSS in all the HTML pages to make them compatible to future browsers.
•Offline Browsing − CSS can store web applications locally with the help of an offline catche.Using of this, we can view offline websites.The cache also ensures faster loading and better overall performance of the website.
•Platform Independence − The Script offer consistent platform independence and can support latest browsers as well.

* colors
* layout
* positioning
* imagery

One of the main reasons for style sheets is to stop the creation of new HTML physical formatting constructs and once again separate style information from document content.
