What's the deal with this loading GIF layout problem?

Styling with CSS:

.smallLoaderBackground
{
    background-image: url('loaderBackground.gif') !important;
    background-position: center center;
    background-repeat: no-repeat;
    position: fixed;
    left: 50%;
    top: 50%;
    height: 50px;
    width: 50px;
    margin: -25px 0 0 -25px;
    z-index: 500;
    text-align: center;
    vertical-align: middle;
}

Adding to HTML:

<asp:UpdateProgress runat="server" ID="UpdateProgress1" AssociatedUpdatePanelID="upForm">
    <ProgressTemplate>
        <div class="smallLoaderBackground">
            <img id="loaderGif" style="padding-top: 9px;" alt="Loader" src="Styles/please-wait.gif" />
        </div>
    </ProgressTemplate>
</asp:UpdateProgress>

Encountering Browser Compatibility Issues:

The design appears correctly in IE, but Chrome displays it poorly by positioning it incorrectly and missing the background. Opera Mobile mirrors IE's display, while Safari on 3GS is a mix of IE and Chrome issues without the background.

Answer №1

Before we proceed, it's crucial to remember that debugging code requires more than just the .NET source code. For better assistance, consider creating a mock-up of your issue on JSFiddle. This approach greatly facilitates identifying specific problems.

Additionally, developing your application/solution in a browser compliant with standards is advisable. Internet Explorer (IE) is notoriously problematic among browsers and basing your design solely on its appearance can lead to cross-browser compatibility issues.

Furthermore, ensure that your overlay is not fixed unless intended to cover the entire screen. The overlay should be absolute to the parent element, and don't forget to include position: relative; for parent elements to make absolute positioning effective. Regarding the use of vertical-align, it seems you might benefit from familiarizing yourself with CSS properties through resources like W3C and Quirksmode.

To summarize: include relevant code snippets, avoid relying on IE, and use absolute positioning when necessary.

While providing solutions, here's an example demonstrating how to create a simple loader overlay. This solution was crafted using Chrome and JSFiddle.
