What causes ASP.net site to appear differently on Internet Explorer, Firefox, and Chrome?

Working on the CSS for a website has led to some unexpected challenges. After sending my HTML and CSS files to another individual to implement into ASP.net, I discovered that the transfer did not go as smoothly as anticipated. The biggest issue I encountered was the fact that when viewed in Chrome, Firefox, and IE8, the website rendered differently in each browser. One specific problem I faced involved a drop-down menu that would appear upon hovering over a link - it worked fine in IE, somewhat in Firefox, but completely broke in Chrome (I have not tested it in Safari or Opera yet). Aligning the design between Firefox and Chrome proved to be quite difficult, as the HTML source code also displayed two distinct pages.

Has anyone come across this issue before? My knowledge of ASP.net is limited, and it appears that the person working with me may be using a WYSIWYG editor to modify my layout (tables appeared randomly throughout the code that I did not place there). In light of these circumstances, what would be the best course of action for me to take? Is this problem solvable, or am I tackling something beyond my capabilities?

Answer №1

Many times, website building tools that show a "What You See Is What You Get" interface may not always create code that works consistently across different browsers. However, there are steps you can take to ensure your site's reliability.

  • One option is to use software such as Adobe BrowserLab (currently offering a free trial) to view your webpage in various browsers simultaneously.
  • Another method is to utilize the W3 Validator to check if your code meets industry standards. Non-compliant code could lead to compatibility issues across browsers.

It's worth noting that ASP.NET allows you to enforce XHTML Transitional or Strict compliance by adjusting settings in the web.config file. To enable this feature, include the following directive:

<xhtmlConformance mode="Transitional"/>

This will help ensure better consistency and performance on your website.

Answer №2

Did your code look good in those browsers before you handed it off to the .NET developer? It seems like the programmer might be causing some issues with your work. ASP .NET shouldn't alter the way your code is displayed... it's basically the Windows version of PHP (in simple terms).

I recommend that you test your code beforehand to ensure it renders correctly. Take some screenshots, and if things start breaking after sending your code to this developer, you can show that it was working fine until he made changes. If that turns out to be the case, then at least you'll know it wasn't your fault. If it was, then we'll need to do more troubleshooting. :)

Do you have any samples you could provide?

Answer №3

I'm seeing two distinct pages in the HTML source as well.

It seems like there may be an issue with the ASP.NET developer's approach. While ASP.NET can be used for browser-specific rendering, perhaps it would be more efficient for them to focus on accurately translating the design you provided. It's typically recommended to ensure your HTML and CSS are correct from the start.
