Showing two DIVs side by side

Following the steps given below you will learn to show several divs side by side. 

 Step 01  Create both HTML & CSS file and link them

First of all create a simple webpage, later create a CSS file and link that to the HTML file.

 Step 02  Add the DIVs inside the <body> and </body> tags

Now add the codes given below inside the <body> and </body> tags of the HTML file.

<div id="main">

<div id="left">Left DIV</div>

<div id="right">Right DIV</div>

</div>

I have used three DIVs above, the first one is the main DIV defined by the id="main" and another two DIVs are inside the main DIV.

 Step 03  Add the CSS codes to the .css file

Add the following CSS codes given below to the  file main.css (or the css file you have created).

#main{

display: -moz-box;

display: -webkit-box;

-moz-box-pack: center;

-webkit-box-pack: center;

-moz-box-orient: horizontal;

-webkit-box-orient: horizontal;

}

#left{

border: 1px solid #333;

width: 40%;

}

#right{

border: 1px solid #333;

width: 40%;

}

 Step 04  Save the works and check the result

Finally save both of the .html and .css files and open the .html file in a browser. There you will get two boxes positioned side by side.

Code Description

Main DIV
We have to use <div id="main"> and </div> for the main div. The attribute id is used to define this DIV. I have used main as the value but you may use anything you like. That means the line may be <div id="div1">. Even you may use the line <div class="main"> instead of the line <div id="main">.

In the .css file I have used the codes given below to format the main DIV. Look, I have used #main to target the div, but you have to use .main if you use <div class="main"> instead of the line <div id="main">. This is the main difference of using id=" " and class=" " attributes.

#main{

display: -moz-box;

display: -webkit-box;

-moz-box-pack: center;

-webkit-box-pack: center;

-moz-box-orient: horizontal;

-webkit-box-orient: horizontal;

}

We have to use the lines -moz-box-orient: horizontal; and -webkit-box-orient: horizontal; to show the DIVs horizontally lying inside the main div. You may also use vertical instead of horizontal to show the divs vertically.

Soon I will add a video here so that you all can understand these properly.

Linking CSS file to a HTML file

---

We have to use CSS to beautify a website and to add various types of effects. We may use CSS codes inside the <head> and </head> tags, but it is not the best practice. That's why we need to know how to create a css file and how to link it with the html file.

 Step 01  Link the css file to the html file

Create a simple webpage and inside the <head> and </head> tag add the line <link rel="stylesheet" type="text/css" href="main.css"/>. The text main.css will be replaced by the name of the CSS file.

 Step 02  Add two more lines

Add two more lines <h1>Header Tag</h1> and <p>This is a paragraph</h1> inside the <body> and </body> tags. Then save the html file.

 Step 03  Create a CSS file

Create a new document using notepad or any other text editor, type the CSS codes given below in it and save it with .css extension. For example: main.css

h1{
color:crimson;
size:32px;
}

p{
color: #fff;
background-color: #333;
}

After adding the codes, save the document as main.css file.

The above codes will format the text inside of the <h1> and </h1> tags as we have defined. And it will also format the text inside of the <p> and </p> tags.

 Step 04  Check the html file whether it is working or not

Finally open the html file in a browser like Google Chrome, Mozilla Firefox etc. But remember to keep both of the html and css files in the same directory.

CSS zoom effect on images of a website

We will create a simple webpage consisting of an image, a message and a title only. Basically we will use some CSS codes to create mouseover zoom effect of images.

 Step 01  First of all create a simple webpage

We need a website to apply the zoom effect. That's why you need to create webpage, but you may apply on your existing website if you have. However, use the following codes given below and create a simple webpage using notepad.

<!DOCTYPE html>

<html> 
   <head>
      <title>CSS Zoom Effect</title>
   </head> 
   <body>

      <img src="name.jpg" width="300px" height="180px"/>      <h1>Hover the mouse on the image</h1>
   </body> 
</html>

The above codes will create a simple webpage with a title, an image and a message.

Note: You have to replace name.jpg with the name of your image and keep the image in the same directory.

 Step 02  Add the CSS codes to zoom the image

Now we need to add the CSS codes given below inside the <head> and </head> tags. You may also add these CSS codes in your .css file.

<style>
img:hover {
-webkit-transform:scale(1.2);
transform:scale(1.2);
}

img {
-webkit-transition: all 0.7s ease;
transition: all 0.7s ease;
}
</style>

 Step 03  Finally save your work and get the effect

After completing all above steps, now save the webpage once again and open it with a browser. Now hover the mouse on the image, it will zoom in.

Feel free to contact with me if face any problem and leave a comment if you like it.

C program to find sphere surface area and volume of a sphere

---

The program given below is a C program that is written to find out the sphere surface area and volume of a sphere. There are rules to find them and we have to use those rules in the program. Let's see the rules...

Area of a Sphere = 4πr2

Volume of a Sphere = (4/3)πr3

According to the above rules, we need to know the r (radius) only to find out the area and volume. Because the value of pi (π) is constant (3.1416).

Here,
Area = ?
Volume = ?
π = 3.1416
r = ?

We have to find out the Area and the Volume, the value of π is fixed and we need to know the radius r only. By the second line #define PI 3.1416 the value of PI has defined 3.1416

By the fifth line float r, area, vol; we have to take three float type variables r, area and vol. r will be used to store the radius of the sphere that we will get from the keyboard using the seventh line scanf("%f", &r);

We have to tell the user to input a value by the sixth line printf("Enter radius of the Sphere: ");

The variables area and vol will be used to store the results.

Later, in eighth and ninth line the program will perform mathematical operations according to the rules described above. The eighth line area = 4*PI*r*r; represent the rule Area of a Sphere = 4πr2 and the ninth line vol = (4/3)*PI*r*r*r; represent the rule Volume of a Sphere = (4/3)πr3

By the tenth and eleventh line the result will be displayed. Generally we use %f to display the float type data, but I have used %.2f  to show immediate two digits of the float number.

#include<stdio.h>
#define PI 3.1416

main()
{
float r, area, vol;

printf("Enter radius of the Sphere: ");
scanf("%f", &r);

area = 4*PI*r*r;
vol = (4/3)*PI*r*r*r;

printf("\nThe area is = %.2f",area);
printf("\nThe volume is = %.2f",vol);
}

Design a webpage using a table

Creating a Simple Table

---

You have to use the codes given below to create a table of two columns and two rows. Step by step we will add more columns and rows to this table and finally we will create a full functional website of several pages. Lets learn how to create a webpage using the codes given below.

<!DOCTYPE html> <html> <head> <title>Learn Website Designing</title> </head> <body> <table align="center" border="1" style="width: 100%;"> <tbody align="center"> <tr><!--codes for the first row--> <td>A</td><td>B</td> </tr><!--end of the codes for the first row--> <tr><!--codes for the second row--> <td>A1</td><td>B1</td> </tr><!--end of the codes for the second row--> </tbody> </table> </body> </html>

Note: The Ash Colored Codes are not important and/or necessary.

You will get a table as showing below.

A	B
A1	B1

Explanation of the codes

---

To create a table I have used the <table> tag in the first line. I have used the attributes align="center", border="1" and style="width: 100%;". That's why the table will be placed in the center position, the width of the table will be 100% according to the webpage size and there will be a border of 1px.

I have used align="center" but you may also use align="left" or align="right". The value for the width attribute may be 80% or 700px. You have to use the closing tag </table> for the opening tag <table>.

In the second line I have used <tbody align="center"> so that all the text of the cells stay in the center position. In the first line I have also used the same attribute align="center" but for the table position only. If you want to show the text in the center position then you have to use <tbody align="center">.

Then in the third line I have used the tag <tr> to create a row and then <td></td> to create a cell. Thus I have used <tr><td>A</td><td>B</td></tr> to create a row and two columns inside of the row. <td>A</td> is for the first column and <td>B</td> for the second column. Thus I have created another row with two columns by the codes <tr><td>A1</td><td>B1</td></tr>.


Add an Extra Row and an Extra Column

---

Now we will add one more column and one more row with the above table. So we have to use the following codes given below in the box.

<tr><!--codes for the first row--> <td>A</td><td>B</td><td>C</td> </tr><!--end of the codes for the first row--> <tr><!--codes for the second row--> <td>A1</td><td>B1</td><td>C1</td> </tr><!--end of the codes for the second row--> <tr><!--newly added codes for the third row--> <td>A2</td><td>B2</td><td>C2</td> </tr><!--end of the codes for the third row-->

Now we will get the table given below.

A	B	C
A1	B1	C1
A2	B2	C2

Create a Table of 10 Rows and 6 Columns

---

Following the above tricks we will now create a new table with six columns and 10 rows. Later we will change it to a general webpage with several buttons, pages etc. Try yourself to create a table as shown below.

A	B	C	D	E	F
A1	B1	C1	D1	E1	F1
A2	B2	C2	D2	E2	F2
A3	B3	C3	D3	E3	F3
A4	B4	C4	D4	E4	F4
A5	B5	C5	D5	E5	F5
A6	B6	C6	D6	E6	F6
A7	B7	C7	D7	E7	F7
A8	B8	C8	D8	E8	F8
A9	B9	C9	D9	E9	F9

If you fail then you may use the codes given below.

<table align="center" border="1" style="width: 100%;"> <tbody align="center"> <tr> <td>A</td><td>B</td><td>C</td><td>D</td><td>E</td><td>F</td> </tr> <tr> <td>A1</td><td>B1</td><td>C1</td><td>D1</td><td>E1</td><td>F1</td> </tr> <tr> <td>A2</td><td>B2</td><td>C2</td><td>D2</td><td>E2</td><td>F2</td> </tr> <tr> <td>A3</td><td>B3</td><td>C3</td><td>D3</td><td>E3</td><td>F3</td> </tr> <tr> <td>A4</td><td>B4</td><td>C4</td><td>D4</td><td>E4</td><td>F4</td> </tr> <tr> <td>A5</td><td>B5</td><td>C5</td><td>D5</td><td>E5</td><td>F5</td> </tr> <tr> <td>A6</td><td>B6</td><td>C6</td><td>D6</td><td>E6</td><td>F6</td> </tr> <tr> <td>A7</td><td>B7</td><td>C7</td><td>D7</td><td>E7</td><td>F7</td> </tr> <tr> <td>A8</td><td>B8</td><td>C8</td><td>D8</td><td>E8</td><td>F8</td> </tr> <tr> <td>A9</td><td>B9</td><td>C9</td><td>D9</td><td>E9</td><td>F9</td> </tr> </tbody></table>

Add <tr></tr> tags to create more rows and used <td></td> tags to create more columns.

Plan for a Webpage

---

The cells A, B, C, D, E and F will be the banner of the webpage and A1, B1, C1, D1, E1 and F1 will be the menu for the webpages. The other cells A2, B2, C2, D2, E2 and F2 will be used to show the current news or important messages. And the cells A3, A4, A5, A6 and A7 will be used for the side menus. And finally the others cells will the main blank portion of the page where the main content will be shown.

A	B	C	D	E	F
A1	B1	C1	D1	E1	F1
A2	B2	C2	D2	E2	F2
A3	B3	C3	D3	E3	F3
A4	B4	C4	D4	E4	F4
A5	B5	C5	D5	E5	F5
A6	B6	C6	D6	E6	F6
A7	B7	C7	D7	E7	F7
A8	B8	C8	D8	E8	F8
A9	B9	C9	D9	E9	F9

The table given below is the expected table to turn it to a webpage.

A
A1	B1	C1	D1	E1	F1
A2
A3	B3
A4
A5
A6
A7
A8
A9

The necessary codes for the above table is given below.

<table align="center" border="1" style="width: 100%;"> <tbody align="center"> <tr> <td colspan="6">A</td> </tr> <tr> <td>A1</td><td>B1</td><td>C1</td><td>D1</td><td>E1</td><td>F1</td> </tr> <tr> <td colspan="6">A2</td> </tr> <tr> <td>A3</td><td colspan="5" rowspan="7">B3</td> </tr> <tr> <td>A4</td> </tr> <tr> <td>A5</td> </tr> <tr> <td>A6</td> </tr> <tr> <td>A7</td> </tr> <tr> <td>A8</td> </tr> <tr> <td>A9</td> </tr> </tbody> </table>

Finding out lost data from pendrive

---

The most common problem we face to use a pendrive is there is nothing in the pendrive. For example: you have stored your project or any other data in a pendrive, but there is nothing when you are going to show that to your teacher and/or boss.

» Then where is the stored data?
» Is the data is still in your pendrive?

First of all, press windows key+E together- the windows explorer will open. Locate your pendrive and make a right click on that, then a pop-up window menu will open. Now click on properties to know how much data is stored there in the pendrive. You will also be able to know if the pendrive is empty.

However, if you think that there is still the data in your pendrive- then follow the steps given below to get back your data.

 Step 01  Find out Folder and search options and click on it
Press Windows Key+E together to open the explorer window. Then click on Organize from the leftmost top corner, a drop-down menu will open. Then click on Folder and search options as shown in the image below.

To do the same thing in different way click on the Start icon (in windows 7) and type folder option into the search box and simply press the Enter key.

 Step 02  Navigate to View tab and change the settings

After clicking on the Folder and search option, a pop-up window will open as like as the image given below. Now navigate to the View tab, there you will get several options to select or deselect.

 

Now you need to do the followings...

» check the radio button Show hidden files, folders, or drives
» uncheck the boxes
    -Hide empty drives in the Computer folder
    -Hide extensions for known file types
    -Hide protected operating system files (Recommended)

After doing the above the window will look like the image given below.

Finally click on the OK button.

 Step 03  Get the data back
Press Windows Key+E if the windows explorer is not opened. Now locate the pendrive and open that again. May be there is nothing yet without some system files. But you will must get an unnamed drive at the top of all. Double click on that to explore, look all of your data is there.

Even if you failed to get your data back and if you sure that you stored the data into the pendrive- then the data may be deleted anyhow. If it happens then recover the lost data now following the first one from the recommended posts.

Create a well-structured webpage using several DIV tags

In the previous posts I have shared the way to create an HTML page and may you also know the basic structure of a simple website. Now in this post I will use some div tags to design a website. Later we will use CSS to customize the divs. The codes are given below is to create a simple webpage only. So use the codes and create a simple webpage first using a text editor like notepade, notepad++ or anyone you prefer.

 Step 01  Create a simple webpage first
First of all you have to create a simple webpage using the codes given below. After creating when you will open the webpage in a web browser then you will get a page as like as the image given below.

Inside the <body> and </body> tags I have written three simple lines inside three different tags. In the next step we will remove all of the codes/text lying inside the <body> and </body> tags. Because our goal is to create a well structured webpage using <div> tags.

<!DOCTYPE html>
<html>
	<head>
		<!--codes to show the title-->
		<title>iDhali</title> 
	</head>
 
	<body>
		<!--header tags-->
		<h1>Hello World!</h1>
		<h2>This is my first webpage</h2>
		<!--parragragh tag-->
		<p>I want to learn website designing completely.</p>
	</body>
</html>

 Step 02  Let's add some <div>s inside the <body> and </body> tags

Now we will add some divs inside the <body> and </body> tags. The divs you need to add are given below.

<div class="wrapper">
	<div class="container">
		<div class="topNav">
		</div>
		<div class="header">
		</div>
		<div class="menu">
		</div>
		<div class="body">
			<div class="contentArea">
			</div>
			<div class="sideBar">
			</div>
		</div>
		<div class="lastAttention">
		</div>
		<div class="footer">
		</div>
	</div>
</div>

 Step 03  Create a CSS file to style the webpage
Now we have to create a new file named style.css/main.css and keep the file into the same directory. Besides we have to link the CSS file to the html file. To do so add the line <link rel="stylesheet" type="text/css" href="main.css"> inside the <head> and </head> tags and save the file index.html

 Step 04  Add some CSS codes
Wait few hours for the next steps. Still editing.... :)
