What happens is that I have my page seen with bootstrap, CSS, HTML5 and jquery. What happens is that when I visualize my page in google chrome it looks perfect but I see it in IE and the styles do not look the way they look in crhome, also some functions of jquery operation do not work either I have tried several things how to reset the styles and other things, but I have not been successful, Ayudaaa ..
There are many things to take into account to optimize compatibility, for example, IE is not able to make a margin between an element and the document, that is, if the first div of your page has a margin-top: 30px ; IE does not know how to work that and it will be shown attached to the top.
Normally for a case like this what was done (and is still done when working with IE) is to put empty containers to occupy spaces.
This is just an example that happened to me, but things like that there are hundreds.
You put more concrete doubts and if it is in my hand I help you.
