Dynamically resize div based on window size

问题

I'm trying to optimise my website for different resolutions. In the center of the website I have a DIV that currently has a fixed size. I'm trying to make its size (and contents) change according to the size of the browser window. How do I do that? This is my website if you want to take a look at its code: http://www.briefeditions.com

回答1:

If you resize the page the div will resize with it and on load of the page.

$(window).on('load resize', function(){
    $('#div').width($(this).width());
});

回答2:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
$(document).ready(function(){
       var windowHeight = $(window).height();
       $('#divID').css('min-height',windowHeight+'px');
});

UPDATE

If you want that site will resize based on browser resize then use % instead of px

CSS:

html {height:100%; overflow:hidden}
body {height: 100%;}

I guess you need screen width and height for client(users) machine.

at onload of page get screen width & height and set those values to divs using jquery/javascript

var userscreen_width,userscreen_height;
userscreen_width = screen.width;
userscreen_height = screen.height;

check this for more info

Keep in mind that in your example iframe also has fixed size. You should also resize it to the parents width. In your example this would work:

$(window).on('load resize', function(){
    $('#content, #content > iframe').width($(this).width());
});

Keep in mind that you must remove all margins, as well as absolute positioning like: top, left, position:absolute from you element styles.

I checked the code from the provided link in question.

Change width to 80% in #content style. And in .wrapper change width to 100%.

You have used mainly 920px for width, so whenever you will resize window the control will not re-size. Use equivalent % instead of 920px;

You can do like this

var width = $(window).width(); 
$("#divId").width(width);
