WDS16 - HTML Forms

In the last article we learned:
  • HTML <meta> tag need
  • All the attributes of <meta> tag including charset
As I said in the last article, today we are going to study something that we see on every website and that is forms. Yes, we see forms everywhere for the purpose of contact, submitting user information, online polls and many other places. So let's see how we can create the form with the help of HTML...

HTML <form> element

HTML <form> element defines a form. All the other form related tags/ form elements will be nested inside it.
There are different types of form elements in HTML which we can use inside <form> element. Let's see one by one:

<input> Element

It is the most important form element. <input> element has attribute type which desides what type of input you are taking.
  • type="text": Defines one-line text input field
  • type="password": Defines password list
  • type="submit": Defines submit button
  • type="reset": Defines reset button
  • type="radio": Defines radio button
  • type="checkbox": Defines checkbox
  • type="button": Defines button customisable by Javascript
  • type="color": Defines color input by using default color picker
  • type="email": Defines email input
  • type="number": Defines number input
and much more...
We are going to see almost all of this one by one. Forms are one of the most important and long concepts in HTML. Every input element has name attribute so that differentiate one input from other and also easily send information to the server.

Text Input

  • Default width of text width is 20 characters. We will see later how we can modify this. 
  • It is usually used to take the input of name, organization name, and other single lines short text.

Radio Button Input

  • It enables the user to select one of given number of options.  To have this functionality, all the input fields must have same name attribute value.
  • value attribute of each input will decide what information to pass when that option is selected.

 The Submit Button

  • It is used to submit the form data to form-handler.
  • Here form-handler means a server page which we accept this form data to store or process it.
  • To decide this form-handler we have to specify action attribute in a <form> tag whose value will decide server page. If not mentioned, server page is same as the current page. In our examples, we will not mention it, as we are not saving this data which requires using backend technology.
  • Another important attribute to <form> tag is a target. This specifies where the form will be submitted that is in the same window, new browser tab or new window. The default is same page window. To open in new browser tab, use target="_blank".
That's all for this article. We will continue HTML Forms in next article. 
Till then #keepCoding.

Python Project - 1 (Password Locker)

Hello reader, this is my first post on this blog. I created this blog for various purposes including First and most importantly improve my coding Help others to learn various concepts in programming  To complete my hobby of blogging So, I am starting various series simultaneously, hope I will able to continue them. In this " Python Project " series, I will create simple python projects and will give step by step procedure to do that. I think you should first try to complete code yourself, then if you get stuck anywhere, feel free to check steps, refer complete code or comment for more help. Let's begin... Idea and Need: You probably have accounts on many different websites. It is a bad habit to have the same password and it is difficult to remember all passwords. So it is a good idea to use "Password Manager Software". So why not create it yourself? So let's see what steps you should follow... Steps: We have to create a menu which has the

WDS85 - Animate the CSS(Part 3)

In the last two articles, we learned about animations in CSS and various ways to customize them with the help of iterations and animation delays. Now in today's article, we are going to learn more about them so that to customize them even more. Let's begin... Reverse Directions and Alternate Cycles The animation-direction property in CSS decides whether we want to play animation forward, backward or in alternate cycles. Following values are possible: normal - This is the default. Animation plays as normal(forward). reverse - The animation plays in reverse direction that is backward. alternate - The animation first plays forward and then backward. alternate-reverse - The animation first plays backward and then forward. Speed Curve of Animation Just like we used various ways to customize transitions in CSS some articles before, same functions can be used to change the speed of the animation. The animation-timing-function property specifies the speed curve o

WDS84 - Animate the CSS(Part2 )

In the last article, we learned about animations in CSS. We learned about the important  @keyframes rule and also seen one example to use it in which we changed the background-color property of div using rules defined in keyframes. Now let's dive deep to learn more about it. Changing Two Properties Simultaneously In the example of the previous article, we just changed background-color using keyframes rule. Let's see the example in which we are changing background-color as well as the position of the div element. To work this properly we are going to position property of div value relative so that we can change it using keyframes. @keyframes myAnimation { 0 % { background-color : blue ; left : 0px ; top : 0px ;} 25 % { background-color : red ; left : 200px ; top : 0px ;} 50 % { background-color : yellow ; left : 200px ; top : 200px ;} 75 % { background-color : green ; left : 0px ; top : 200px ;} 100 % { background-
