It is common that the same contact form looks different depending on the browser. Especially when you have date input fields or numerical value input fields in the form, you may see a great difference. If it is just a visual difference, and you can use the form without problems, you don’t have to worry about that. It is completely normal.

If it is not just a visual difference and is preventing use of the form, the difference of behavior between browsers might indicate that there are errors in HTML, CSS, or JavaScript used on the page. In this case, you need to debug them. Utilize developer tools that your browser provides, or ask for help on the support forum.
