I am trying to create my first web page. The style part of the code was suposed to change the background color, but it dont. 

I think the code works so why dont it show up when I use it? 

By mistake I changed the default way to open css files to "skype" and this created a problem. I changed it to notepad, but that did not fix the problem and I dont know what should be the default program to open it.

```
<!doctype html>
<html>

  <head>
    <title> My web Page </title>  
    <style>
      body {
      background:red;
      }
    </style>
  </head>

  <body>   
    <h1>  My webSite</h1>
    <h2> This is my homepage content</h2>
   </body>

</html>

Use `sortBy`

```
val rdd : RDD[((String,Int),Int)] = ???

rdd.sortBy{case ((name,age),_) => name}

```

Sort by age:

```
rdd.sortBy{case ((name,age),_) => age}

```
`sparkContext.parallelize(Array( ("Sam", 23),("Ram", 32),("Dan", 25) )).sortBy(_._1)//If it's inverted order,input false ,If you pass the age _1 to _2
.foreach(println)`
