Welcome Again all,
Today I am Going To Start New Topic
Very Very Important as a Web Developer
For HTML which covers Forms.
Let’s Start...


  1. Form Elements select and Text Area
  2. Input Elements
  3. Input Elements Attributes
Form elements are such element which we used for creating our HTML form like Some Elements input box,dropdown select,Buttons,Textarea.
Input Box – For Simple input of data in any format.
Select Dropdown – For Selecting Item in a list of items
textarea – For Large Area of Input Contents ,Description Message which is  used to display our data in also multiline.
Button – For Submit our Form or Simple Button For Any Events.

List of Form Elements.

  1. <form>
  2. <select>
  3. <input>
  4. <textarea>
  5. <button>
  6. <option>
  7. <datalist>
  8. <optgroup>
  9. <button> 

<!DOCTYPE html>

Input Box <input type="text" name="text">
    DropDown Select <select name="text">
    Text Area<textarea cols="50" rows="5">I m a text area</textarea>

Simple Login Form Example

<!DOCTYPE html>
<title>Form Elements</title>
<form action="login.php" method="post">
Email<br> <input type="email" name="email" placeholder="Email">
    Password <br> <input type="password" name="Password" placeholder="Password">
 <button type="submit" name="button">Login</button>



html login form

From line <form> - Here is form beginning form elements pass all data to new page on submitting. Form elements pass only that data which is child element of form.
E.g <form>child Elements</form>
method= method is default get but we can use get or post.
When we use get our data pass through url which we see in url and post 
pass data hidden.
action = action is our url for submitting data on that page like any server side page where it catch that data.( which we see in php tutorial) for now we just pass and server side language catch it.

Other line after that are data elements which contain in its its variable and variable name is name=”value” this value is the variable name which we catch in server side.

Submit = button submit is used to submit our its very important for submitting our forms.


Here is a list of Input Types Elements like radio,checkbox,button,date,select

select element and properties
select has a list of child  elements which values we defined inside option element when we submit the form the selected values pass through the form
<option>First</option>   and <option value=”1”>First</option> 
Here you two types of option i declare both is same but if we dont defined (set value=”value”) then option text value will be passed else value attribute value pass.

We can also make default selection of any element by using attribute
in option element

We can set the size of select box  like display more than one value at a time  by using.
size=”n” where n= no. Of elements to display 

We can also make multiple selection this time the value will pass in array format.
By using multiple=”multiple” but for using mutiple we have to change name  in array for like my variable name is : -

then i have to change it to

if we don’t do that then we only get single selected value only

        <select name="fruit">
         <select name="animal" size="4">
