How do I get TinyMCE to allow text-align when H1 is the root element?

I have an h1 or h2 etc. tag as the root element which I apply a TinyMCE inline editor to.

I want to allow the user to align this text to the right or to center it.

However, TinyMCE only allows h1s to have the text-align attribute when it is contained within a div.

Alternatively, is there a way to have a div, which is only allowed to have a single h1 element, and no other elements?

 

I have tried the following option in tinymce.init after making the root element a div instead of an h1.

valid_elements: 'h1'

which didn't work, and then I tried

valid_elements: 'h1/p'

which does convert all ps to h1s, but only after the editor is closed and reopened, not while the user is typing.

The problem here is that when you apply the text-align property it's wrapping the text in a span tag (or other tag.. i.e. strong, etc). This works for most formatting but doesn't work for text-align. The reason why is because the tex-align has to be applied to the parent tag, not interior of it. It's like if I told you to center a square within another square that's the exact same size. It's the same if you left-align, right-align or center-align because there's no space to move around in. You can see what I mean on this fiddle: http://jsfiddle.net/f8meyapv/1/

I have two solutions for you.

First solution:

Try to surround the inside of the elements (h1, h2, etc) with a div and give it a class like editable-inner that you target. The only downside is that it will wrap your inside content in p tags (<h1><p>content</p></h1>). However, it's a quick and easy solution. Don't forget to update your selector in the javascript!

JS:

my_wysiwyg_settings = {
    selector: "h1.wysiwyg>div.editable-inner",
    ...
}

HTML:

<h1 class='wysiwyg'>
   <div class='editable-inner'>
       <!-- WYSIWYG content is added here -->
   </div>
</h1>

When initiated, it turns into this:

<h1 class='wysiwyg'>
   <div class='editable-inner'>
        <p style="text-align:center;">Some content!!</p>
   </div>
</h1>

Second solution You can also make a custom button which adds a class to the outer parent tag instead of surrounding the inner contents with a

HTML:

<h1 class='wysiwyg'>
   <!-- WYSIWYG content is added here -->
</h1>

JS:

     my_wysiwyg_settings = {
        selector: "h1.wysiwyg",
        toolbar: "myHeadingAlignLeft myHeadingAlignCenter myHeadingAlignRight", //add custom buttons to toolbar
        setup: function(editor) {  //define button function
            editor.addButton('myHeadingAlignLeft', {
                icon: 'alignleft',
                onclick: function() {
                    addClass(editor.id,'align-left'); //back-end function below
                    // or use this front-end function: //$('#' + editor.id).css({'textAlign' : 'left'});
                }
            });

        editor.addButton('myHeadingAlignCenter', {
            icon: 'aligncenter',
            onclick: function() {
                addClass(editor.id,'align-center');
            }
        });

        editor.addButton('myHeadingAlignRight', {
            icon: 'alignright',
            onclick: function() {
                addClass(editor.id,'align-right');
            }
        });    
...
};

function addClass(id, className) {
    $.ajax({
        type: 'POST',
        ... //rest of ajax request here...
    });
}

CSS:

.align-left{ text-align:left;}
.align-right{text-align:right;}
.align-center{text-align:center;}
