When I open chrome developer console and type:
document.firstElementChild.lastElementChild.lastElementChild.lastElementChild.innerHTML = "Steven"
the text "Third" changes to "Steven".
There are two child elements of HTML, the head and the body. So, why doesn't the code 'firstElementChild' target the the head element, since that's the first element?

I'm unable to toggle my navbar button. I'm not sure if it's a bug in Leaf. I've implemented Bootstrap and CSS in the right order. Try and run this code. Don't forget to resize your browser window to mobile or tablet view in order to show navbar toggle button.
Here's my leaf code:

In Safari's Inspect element, my html document is rendered in the right order. But, I've no clue why the click on navbar toggle isn't working.
As far as I remember using Vapor 4 leaf renderer there is a bug about #. They are always interpreted as the beginning of a leaf tag.
The simplest workaround is to escape them with a \ : data-target="#navbarCollapse" become data-target="\#navbarCollapse"
I believe there is a bug in Leaf parser, and the # in data-target="#navbarCollapse" gets misinterpreted. The way I have solved it is to change data-target to data-target=".navbarCollapse" and to modify class attribute of navbarSupportedContent div element from <div class="collapse navbar-collapse" id="navbarSupportedContent"> to <div class="collapse navbar-collapse navbarSupportedContent" id="navbarSupportedContent">. Not the best of workaround, but it does the trick until the Leaf parser is modified.
My test is very basic like this web page below. I don't understand why on iphone 6 or 5 Foundation seems not working. Do you have any idea ?

The result is medium any way flex grid or x-y grid.
I use sass for my project but for this test i use directly the full official cdn file. I still get same result.
I need a program that includes two buttons to increase and decrease the number and display it
As well as storage and display number after close and open app
for storage data you can use angular-local-storage for get https://github.com/grevory/angular-local-storage
for load data use $scope.storageValue = localStorageService.get('StoreData');
for save data use localStorageService.set('StoreData',$scope.storageValue);

Sorry, My bad. I hadn't added the angular module!
mmenu crashes the page when used with Google Publisher Tags (async), as soon as the page loads the css formatting and html structure seems to be lost and all further javascript execution stops. It can be reproduced by adding a google publisher tag in the demo file of mmenu download.
