How to put a text box next to 2 open answer options

Hey there! What if you want to put a text box next to answer option (as opposed to below it), when there are 2 other specify boxes in one question?
I have the following code snippet:

<style type="text/css">
.LabelWrapper
{
display:inline-flex;
}
</style>

But the output looks ugly:

!

I think I might need to adapt 'display:inline-flex' - but I don't know css well enough to figure out the problem ...

Very happy about support!
