HTML5 New Way of Declaring Attributes

HTML5 has introduced 4 different ways to declare an attribute, let’s have a look at them.

Type

Example

Unquoted

Double-quoted

Single-quoted

HTML5 has introduced few new input types as well; let’s have a look at them.

color
datetime
datetime-local
email
month
range
search
tel
time
url
week

HTML5 codes for the above input types are as below

 
<!DOCTYPE html> 
 <html> 
 <head> 
 <meta charset="utf-8" /> 
 <title>HTML5</title> 
 <link href="StyleSheet.css" rel="stylesheet" /> 
 </head> 
 <body> 
 <form> 
 <h3>Color:</h3> 
 <input type="color" name="differentColor"> 
 
 <h3>Date:</h3> 
 <input type="date" name="whichDate"> 
 
 <h3>DateTime:</h3> 
 <input type="datetime" name="todayDatetime"> 
 
 <h3>DateTime-Local:</h3> 
 <input type="datetime-local" name="local"> 
 
 <h3>Email:</h3> 
 <input type="email" name="personalEmail"> 
 
 <h3>File:</h3> 
 <input type="file" name="attachment"> 
 
 <h3>Month:</h3> 
 <input type="month" name="auspiciousMonth"> 
 
 <h3>Number:</h3> 
 <input type="number" name="quantity"> 
 
 <h3>Range:</h3> 
 <input type="range" name="listOfNumbers"> 
 
 <h3>Search:</h3> 
 <input type="search" name="localSearch"> 
 
 <h3>Tel:</h3> 
 <input type="tel" name="telephone"> 
 
 <h3>Time:</h3> 
 <input type="time" name="userTime"> 
 
 <h3>Url:</h3> 
 <input type="url" name="siteUrl"> 
 
 <h3>Week:</h3> 
 <input type="week" name="valentineWeek"> 
 </form> 
</body> 
 </html>

New input types have given us the liberty to map almost any kind of input to the server side code without having to write mapping/plumbing code at the front end.Also these provide some kind of validations as well.

For ex: input type=”email”, it validates the standard email pattern.
