Why does layout collapse in bitrix editing mode?

Question

1C-Bitrix

Hello, here is the code:

<div class="h1">
<? $APPLICATION->IncludeFile("include/h1.php", Array(), Array("MODE"=>"html")); ?>
</div>

<div class="description">
<? $APPLICATION->IncludeFile("include/description.php", Array(), Array("MODE"=>"html")); ?>
</div>

In edit mode, anywhere if you click 2 times, then editing the h1 file will open, in general, it occupies the entire page. (I can’t screenshot it, so I’ll draw it):

There is also a problem with inline blocks, when, for example, only a phone number is in the includes, it jumps to another line, and the layout breaks.
How to properly connect the embedded area so that nothing breaks?
Tell me please

Answer 1

you have an error in your code:

<div class="h1">
<? $APPLICATION->IncludeFile("include/h1.php", Array(), Array("MODE"=>"html")); ?>
</h1>

and Bitrix in edit mode additionally wraps div...
