WDS18 - Little More About HTML Forms

In the last article we learned:
  • Input type Reset
  • Input type Password
  • Input type Color
  • Input type Date
  • Input type Email
  • Input type Checkbox
Including the first 3 input fields learned in the first article about HTML forms, now we can use 9 various types of input fields in our forms. There are more fields, some of which are not very important but you can check all other fields on Internet, but what we have learned about input fields is more than enough.
Now let's see some input attributes so that we can customise our inputs.

The value Attribute

It is used to specify the initial value of an input field.
<input type="text" name="lastname" value="Ronaldo">

The readonly Attribute

It is used to specify that input field can not be edited that is it is fixed.
<input type="text" name="lastname" value="Ronaldo" readonly>

The disabled Attribute

It is used to disable specific input field. The disabled input field can not be clicked or used. Its value will not be sent while submitting form.
<input type="text" name="lastname" value="Ronaldo" disabled>

The size Attribute

It specifies size of input field in number of characters. Default is 20 characters.
<input type="text" name="lastname" value="Ronaldo" size="30">

The maxlength Attribute

It specifies maximum allowed length for the input field.
<input type="text" name="lastname" maxlength="30">

The autocomplete Attribute

This HTML5 special attribute enables browser to automatically complete input based on previously entered values.
<input type="email" name="mymail" autocomplete="on">

The min and max Attributes

This attribute is available for folloeing input fields:
  • number
  • range
  • date
 <input type="number" name="cameras" min="1" max="4"> 
 <input type="date" name="bday" min="2000-01-01">  

The placeholder Attribute

It is used to specify hint in input field or sample input user can enter.
<input type="text" name="myname" placeholder="Enter your name">

The required Attribute

It is used to specify that form can not be submitted without
<input type="text" name="myname" placeholder="Enter your name">
Although I have not shown live code examples, I encourage you to try this example out. The above-mentioned input attributes are more than enough and can be applied to various types of inputs(excluding some special like min and max).
That's all for today. In the next article, we will some more things about forms and will most probably finish HTML forms. 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-
