Website working perfectly with IE8 but not working when using the compatibility view

Question

I've created a website ( main page ) that works perfectly on IE8 but not when I'm using the compatibilty view to emulate IE7 (the design of the page is messy).

Compatibility View Screenshot:

(Cropped form elements in "Votre situation familiale" section, tabs floating at top of page, mis-aligned "Demande de devis" button)

I really have no idea of how to correct this and I'm wondering if you guys have already met a similar situation and how you solved it.

通读了IE CSS常见错误列表，了解布局并考虑使用条件注释将不同的样式表提供给IE的较早版本。
