CSS ─ Syntax

A CSS comprises of style rules that are interpreted by the browser and then applied to the corresponding elements in your document. A style rule is made of three parts:

Selector: A selector is an HTML tag at which a style will be applied. This could be any tag like or etc.

Property: A property is a type of attribute of HTML tag. Put simply, all the HTML attributes are converted into CSS properties. They could be color, border, etc.

Value: Values are assigned to properties. For example, color property can have the value either red or #F1F1F1 etc.

Syntax– selector { property: value }

Example: You can define a table border as follows:
table{ border :2px solid #C00; }

Here table is a selector and border is a property and the given value 2px solid #C00 is the value of that property.

Advantages of CSS

  • CSS saves time – You can write CSS once and then reuse the 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 the 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 cellphones or for printing.
  • Global web standards – Now HTML attributes are being deprecated and it is being recommended to use CSS. So it’s a good idea to start using CSS in all the HTML pages to make them compatible with future browsers.

Introduction of Css

Cascading Style Sheets, fondly referred to as CSS, is a simple design language intended to simplify the process of making web pages presentable.
CSS handles the look and feel part of a web page. Using CSS, you can control the color of the text, the style of fonts, the spacing between paragraphs, how columns are sized and laid out, what background images or colors are used, as well as a variety of other effects.
CSS is easy to learn and understand but it provides a powerful control over the presentation of an HTML document. Most commonly, CSS is combined with the markup languages HTML or XHTML.

What is Database Management System DBMS

 02 Sep  Admin

DBMS stands for Database Management System. DBMS is a software package designed to define, manipulate, retrieve and manage data in a database. We can break it like this DBMS = Database + Management System. Database is a collection of data and Management System is a set of programs to store and retrieve those data. It also defines rules to validate and manipulate this data.

Hierarchical model in DBMS

 02 Sep Admin

In hierarchical database model the data are organized into a tree-like structure where each record is having one parent record and many children.This model structure allows the one-to-one and a one-to-many relationship between two/ various types of data.The main drawback of this model is that, it can have only one to many relationships between nodes.

Python For Loops

 28 Aug   Admin

for <var> in <iterable>:
    <statement(s)>

  is a collection of objects—for example, a list or tuple. The  in the loop body are denoted by indentation, as with all Python control structures, and are executed once for each item in . The loop variable  takes on the value of the next element in  each time through the loop.

Example–

 a = ['apple', 'banana', 'mango']
 for i in a:
    print(i)

Output-
apple
banana
mango
In this example, <iterable> is the list a, and <var> is the variable i. 
Each time through the loop, i takes on a successive item in a, 
so print() displays the values 'apple', 'banana', and 'mango', respectively.
 A for loop like this is the Pythonic way to process the items in an iterable.

Iterables

In Python, iterable means an object can be used in iteration. If an object is iterable, it can be passed to the built-in Python function iter(), which returns something called an iterator. Yes, the terminology gets a bit repetitive.

Python While Loops

28 Aug   Admin

while <expr>:
    <statement(s)>

<statement(s)> represents the block to be repeatedly executed, often referred to as the body of the loop. This is denoted with indentation, just as in an if statement.

The controlling expression, <expr>, typically involves one or more variables that are initialized prior to starting the loop and then modified somewhere in the loop body.

When a while loop is encountered, <expr> is first evaluated in Boolean context. If it is true, the loop body is executed. Then <expr> is checked again, and if still true, the body is executed again. This continues until <expr> becomes false, at which point program execution proceeds to the first statement beyond the loop body.

Example–

  n = 5
  while n > 0:
     n -= 1
    print(n)

Output-

 4
 3
 2
 1
 0

Here’s what’s happening in this example:

  • n is initially 5. The expression in the while statement header on line 2 is n > 0, which is true, so the loop body executes. Inside the loop body on line 3, n is decremented by 1 to 4, and then printed.
  • When the body of the loop has finished, program execution returns to the top of the loop at line 2, and the expression is evaluated again. It is still true, so the body executes again, and 3 is printed.
  • This continues until n becomes 0. At that point, when the expression is tested, it is false, and the loop terminates. Execution would resume at the first statement following the loop body, but there isn’t one in this case.
