What are the best practices for creating a webpage that adjusts its layout when the browser window size is changed?

What is the best way to create a web page that adjusts its layout when the browser window is resized?

I have experimented with using tables and CSS float sections to organize my page elements, but I want the display to adapt as the browser window size changes.

I currently have a working solution involving AJAX PRO and DIVs with overflow:auto, along with an onwindowresize hook. However, I find this method cumbersome. Is there a more efficient approach?

  • Thank you to everyone who has provided suggestions so far. I plan to test out various methods and select the most effective one as the solution for this issue.

  • Using CSS and percentages seems to be the most successful option, which aligns with what I originally implemented. By utilizing a visibility:hidden div set to 100% by 100%, I can determine the client area of the window (a challenge in some versions of IE). Additionally, an onwindowresize JavaScript function triggers the AJAXPRO methods to redraw the layout-cell contents based on the new resolution.

EDIT: I apologize for any confusion earlier. My goal was to create a 'liquid layout' where the main elements ('panes') would adjust their size as the browser window resized. I discovered that by making an AJAX call to refresh the 'pane' contents after resizing and keeping overflow:auto activated, I could prevent scrolling issues.

Answer №1

Instead of specifying a fixed width in CSS like "width: 200px", consider using relative measurements such as "width: 50%"

By using percentages, the element will take up 50% of its parent container's width. For example:

<body>
 <div style="width:50%">
  <!--some stuff-->
 </div>
</body>

The div will always occupy half of the window horizontally.

If you don't have a particular need for JavaScript in this context, it may be unnecessary to use it. While tabular layouts are commonly used for creating fluid layouts in html, using div layouts with css can also achieve the same effect. You can refer to for more information.

Answer №3

It seems like you are interested in exploring a fluid CSS layout. To find more information on this topic, simply search for fluid CSS layouts online to uncover a plethora of resources. You may also benefit from reading this related question for additional insights.

Answer №4

When it comes to implementing a web page, the choice of using CSS or not depends on the specific requirements of the project. Generally speaking, opting for 100% CSS is recommended. When sizing elements that will display text, it's advisable to use text-oriented units such as em and ex instead of pixels.

Floats can be tricky, especially for beginners in CSS. Even experienced developers may find them confusing at times. It's best to avoid floats whenever possible and focus on modifying the display property of the element being worked on.

By following these guidelines and seeking solutions online when facing challenges, you can create web pages that are responsive to browser resizing and allow for zooming in and out by adjusting text size. While achieving this level of design perfection may require significant effort, it ensures a robust layout that can withstand complex arrangements.

Consider your objectives when designing a website - whether it's for fun, profit, or both. Finding a balance between adhering to CSS principles and utilizing practical hacks to improve efficiency is crucial. If strict accessibility standards are not necessary for your site, prioritize functionality that serves your business goals. Once the essential aspects are covered, feel free to indulge in creative experimentation with extra features.

Answer №5

Another important factor to keep in mind is that JavaScript doesn't update in real-time during window resizing, resulting in a visible delay or choppiness. In contrast, with a flexible CSS layout, screen elements will update rapidly for a smooth transition.

Answer №6

The most effective method I've found for achieving this is utilizing the YUI CSS Tools and implementing percentage-based layouts. With YUI Grids, you have the flexibility to create fixed width or fluid designs by specifying column sizes as fractions of the available space. The YUI Grids Builder can assist in organizing your layout seamlessly, while YUI Fonts provides excellent control over font sizes. Referencing cheat sheets can also be helpful in understanding layout techniques and determining appropriate percentages for font sizes based on pixel measurements.

While this approach allows for scalable positioning, adapting the entire site, including font sizes, to resize with the browser window presents a more challenging task. It may require developing a custom browser plugin, which could limit portability. If the site will be accessible on the internet rather than just an intranet, it's important to consider alternative solutions that provide better compatibility across different browsers.

Answer №7

After following the standard solution guidelines, I encountered compatibility issues with either Firefox or IE. So, after some experimentation, I came up with this CSS code. Notice how the margins are set to half of the desired size and negative.

<head><title>Centered</title>
<style type="text/css">
body { 
        background-position: center center;
        border: thin solid #000000;
        height: 300px;
        width: 600px;
        position: absolute;
        left: 50%;
        top: 50%;
        margin-top: -150px;
        margin-right: auto;
        margin-bottom: auto;
        margin-left: -300px;
    }
</style></head>

I hope this solution proves useful to you.

When designing a webpage, it's important to use percentages for responsive design. Imagine you have a "main panel" that contains all the content of your page. You want this panel to always be centered in the window and take up 80% of the window's width.

To achieve this, simply add the following CSS code:
#centerpanel{ margin: auto; width: 80%; }

Voila! Your content is now perfectly centered within the window!

Answer №9

Appreciate all the feedback! It seems like the tedious tasks I had to complete were necessary. The code below is functional (at least on my end) in both IE and Firefox. Perhaps I'll turn this into an article for CodeProject.com later on ;-)

This snippet of JavaScript should be placed in the <head> section:

<script type="text/javascript">
var tmout = null;
var mustReload = false;

function Resizing()
{
    if (tmout != null)
    {
        clearTimeout(tmout);
    }
    tmout = setTimeout(RefreshAll, 300);
}
function Reload()
{
    document.location.href = document.location.href;
}

// Additional script goes here
</script>

The opening of the <body> looks like this:

<body onload="RefreshAll();">
    <div id="divBackdrop"
        style="width:100%; clear:both; height: 100%; margin:0; padding:0; position:absolute; top:0px; left:0px; visibility:hidden; z-index:0;">
    </div>

The DIVs are using float left for layout purposes. To prevent wrapping, heights and widths were set to percentages slightly below the full amount (e.g., 99.99%, 59.99%, 39.99%), likely due to borders on the DIVs.

Lastly, after the content section, there's another JavaScript block for handling refreshes:

// Insert additional JavaScript code here

It may not be pretty, but it gets the job done - which ultimately is what counts ;-)

Try using ems as your unit of measurement. For inspiration, check out the websites jontangerine.com and simplebits.com. If you're interested in learning more, read The Incredible Em & Elastic Layouts with CSS by Jon Tan

< body onresize="resizing()" onload="resizing()" > CONTENT < /body > 

    /**** Resizing Page Function ****/

    function resizing() 
    {
        var height = getHeight();
        var width = getWidth();

        document.getElementById("content").style.height = (height - 4) + "px";
    }

    function getHeight() 
    {
        var windowHeight=0;
        if (typeof(window.innerHeight)=='number') 
        {
            windowHeight = window.innerHeight;
        }
        else {
            if (document.documentElement && document.documentElement.clientHeight) 
            {
                windowHeight = document.documentElement.clientHeight;
            }
            else 
            {
                if (document.body && document.body.clientHeight) 
                {
                    windowHeight = document.body.clientHeight;
                }
            }
        }
        return windowHeight;
    }

The project I'm currently working on requires some adjustments in terms of width, the height is functioning well until now ^^
