How to auto adjust the div size for all mobile / tablet display formats?

I have designed a page where four

div
tags are there in the page. If I test the page in mobile phone (5 inch) it fits the page perfectly, If I test the same page in tablet the page fits with in 30% of the screen. So how can I set the
div
size so that it will fit for all type of screens.

HTML:

<div class="bubble0" align="center">
<h3>Three Levels </h3>
</div>
<div class="bubble" align="center"> </div><br/><br/>
<div class="bubble1" align="center"> </div><br/><br/>
<div class="bubble2" align="center"> </div><br/><br/>
<button>Play</button>


Any suggestions please,

This is called Responsive Web Development(RWD). To make page responsive to all device we need to use some basic fundamental such as:-

1. Set the viewport meta tag in head:

<meta name="viewport" content="width=device-width,height=device-height,initial-scale=1.0"/>

2.Use media queries.

Example:-

/* Smartphones (portrait and landscape) ----------- */
@media only screen 
and (min-device-width : 320px) 
and (max-device-width : 480px) {
/* Styles */
}

/* Smartphones (landscape) ----------- */
@media only screen 
and (min-width : 321px) {
/* Styles */
}

/* Smartphones (portrait) ----------- */
@media only screen 
and (max-width : 320px) {
/* Styles */
}

/* iPads (portrait and landscape) ----------- */
@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) {
/* Styles */
}

/* iPads (landscape) ----------- */
@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : landscape) {
/* Styles */
}

/* iPads (portrait) ----------- */
@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : portrait) {
/* Styles */
}

/* Desktops and laptops ----------- */
@media only screen 
and (min-width : 1224px) {
/* Styles */
}

/* Large screens ----------- */
@media only screen 
and (min-width : 1824px) {
/* Styles */
}

/* iPhone 4 ----------- */
@media
only screen and (-webkit-min-device-pixel-ratio : 1.5),
only screen and (min-device-pixel-ratio : 1.5) {
/* Styles */
}

3. Or we can directly use RWD framework:-
