Q:

You want only a vertical scrollbar and no horizontal scrollbar on your page. How would you do it?

Answer

- This can be done by defining the frame with SCROLLING = auto and having content to just fit into this frame. 


- SCROLLING="yes" gets the scroll bar on both the sides, even when not needed. 


- SCROLLING="no" doesn’t get the scrollbars at all, even when they are needed.

Q:

What is session storage and how can you create one?

Answer

Session storage is same like local storage but the data is valid for a session. In simple words the data is deleted as soon as you close the browser.


To create a session storage you need to use “sessionStorage.variablename” . In the below code we have a created a variable called as “clickcount”.


If you refresh the browser the count increases. But if you close the browser and start again the “clickcount” variable starts from zero.


if(sessionStorage.clickcount)


{


sessionStorage.clickcount=Number(sessionStorage.clickcount)+1;


}


else


{


sessionStorage.clickcount = 0;


}

Q:

What is local storage concept in HTML 5?

Answer

Many times we would like to store information about the user locally in the computer. For example let’s say user has half-filled a long form and suddenly the internet connection breaks off. So the user would like you to store this information locally and when the internet comes back.He would like to get that information and send it to the server for storage.


Modern browsers have storage called as “Local storage” in which you can store this information.
