Styled Textbox using CSS

The following CSS will style the textbox.

.styled-textbox{
    border:1px solid #d1c7ac;
    width: 200px;
    height:30px;
    padding:5px;
    background: -moz-linear-gradient(center top , #FFF, #EEE 1px, #FFF 25px) repeat scroll 0% 0% transparent;
}
.styled-textbox:hover{
    border:1px solid #25A6E1;
}
.styled-textbox:focus{
box-shadow: 0px 0px 5px #00AFC7;
border:1px solid #25A6E1;
}

Preview:

Now to style any textbox as above add above css class(.styled-textbox) to it .For example:

In HTML:
<input type="text" id="textbox1" placeholder="Type Here" class="styled-textbox" />

In ASP.NET:
<asp:Textbox ID="Button1" runat="server" placeholder="Type Here" CssClass="styled-textbox" />

Styled button using CSS

The following css class will style the button.

.styled-button-green {
    background:#5CCD00;
    padding:10px 15px;
    color:#fff;
    font-family:'Helvetica Neue',sans-serif;
    font-size:16px;
    border-radius:5px;
    border:1px solid #459A00
}

Preview:

Now to style any button, assign the above css class(styled-button-green) to the button. For example:

In HTML:
<input type="button" id="Button1" class="styled-button-green" />

In ASP.NET:
<asp:Button ID="Button1" runat="server" CssClass="styled-button-green" />

Lengths and percentages in CSS

There are many property specific units for values used in CSS, but there are some general units that are used in a number of properties.

em

em is unit for the calculated size of a font. For example:

font-size:2em;

Here 2em, is two times the current font size.

px

px is unit for pixels. For example:

font-size:20px;

pt
pt is unit for points. For example:
font-size:20pt;

%
% is unit for percentage. For example:
font-size:20%;

Other units include pc(picas), cm(centimetres), mm(millimetres) and in(inches).

When a value is zero, you need not to state a unit.

It is generally accepted that 'em' or '%' are the best units to use for font-sizes, rather than 'px', which leads to non-resizable text in most browsers.

CSS Selectors, Properties, and Values

Selectors

Whereas HTML has tags, CSS has selectors. Selectors are the names given to styles in internal and external style sheets.

Tag Selector

We can use HTML tags as CSS selectors. For example:

p{

color: blue;

}

Here all HTML 'p' tags are referenced. It will make the font-color of each p tag as blue

Another example inculde:

body{

backround-color:blue;

}

ID selector

We can assign a HTML tag a ID and then can use it as a selector. For example:

<P id="Para1">This is a paragraph</P>

then we can use it as:

#Para1{
color:blue;
}

# is necessary. ID should be unique, i.e. no two tags can have same ID

Class Selector

We can assign a class to HTML tags and then can use it as a selector. For example:

<P class="P1">Paragraph1</P>
<P class="P1">Paragraph2</P>
<P>Paragraph3</P>

then we can use it as:

.P1{
color:blue;
}

It will be as:

Paragraph1
Paragraph2
Paragraph3

Properties

For each selector there are properties inside curly brackets, which simply take the form of words such as color,background-color, font-size etc.

These are the properties of HTML tags which can be changed. For example, to change the color of text use 'color' , to change the size of text use 'font-size' , to change the background color use 'background-color' and many more.

Values

A value is given to the properties following a colon, and semicolon seperates the properties. For example:

body{
font-size:0.8em;
color:blue;
}

Syntax of CSS

Syntax of css is:

selector{
property1:value;
property2:value;
..
..
propertyN:value;
}

CSS syntax includes the following things:

Selector
Property
Value

What is Cascading Style Sheets (CSS)?

A Style Sheet Language, or style language, is a computer language that expresses the presentation of structured documents. One attractive feature of structured documents is that the content can be reused in many contexts and presented in various ways. Different style sheets can be attached to the logical structure to produce different presentations.

Style Sheets enforce standards and uniformity throughout a website.

Style Sheets are said to cascade when they combine to specify the appearance of a page.

Cascading Style Sheets (CSS) is a style sheet language used for describing the look and formatting of a document written in a markup language. While most often used to change the style of web pages and user interfaces written in HTML and XHTML, the language can be applied to any kind of XML document, including plain XML, SVG and XUL. Along with HTML and JavaScript, CSS is a cornerstone technology used by most websites to create visually engaging webpages, user interfaces for web applications, and user interfaces for many mobile applications.

Types of SQL keys

We have following types of keys in SQL which are used to fetch records from tables and to make relationship among tables or views.

Super Key

Super key is a set of one or more than one keys that can be used to identify a record uniquely in a table.Example :Primary key, Unique key, Alternate key are subset of Super Keys.
Candidate Key

A Candidate Key is a set of one or more fields/columns that can identify a record uniquely in a table. There can be multiple Candidate Keys in one table. Each Candidate Key can work as Primary Key.
Primary Key

Primary key is a set of one or more fields/columns of a table that uniquely identify a record in database table. It can not accept null, duplicate values. Only one Candidate Key can be Primary Key.
Alternate key

A Alternate key is a key that can be work as a primary key. Basically it is a candidate key that currently is not primary key.
Composite/Compound Key

Composite Key is a combination of more than one fields/columns of a table. It can be a Candidate key, Primary key.
Unique Key

Uniquekey is a set of one or more fields/columns of a table that uniquely identify a record in database table. It is like Primary key but it can accept only one null value and it can not have duplicate values.
Foreign Key

Foreign Key is a field in database table that is Primary key in another table. It can accept multiple null, duplicate values.

Necessary and Sufficient Conditions for a Deadlock

Coffman (1971) identified four (4) conditions that must hold simultaneously for there to be a deadlock.

1. Mutual Exclusion Condition: The resources involved are non-shareable.
Explanation: At least one resource (thread) must be held in a non-shareable mode, that is, only one process at a time claims exclusive control of the resource. If another process requests that resource, the requesting process must be delayed until the resource has been released.
2. Hold and Wait Condition: Requesting process hold already, resources while waiting for requested resources.
Explanation: There must exist a process that is holding a resource already allocated to it while waiting for additional resource that are currently being held by other processes.


3. No-Preemptive Condition: Resources already allocated to a process cannot be preempted.
Explanation: Resources cannot be removed from the processes are used to completion or released voluntarily by the process holding it.


4. Circular Wait Condition: The processes in the system, form a circular list or chain where each process in the list is waiting for a resource held by the next process in the list.
