Answer 1

SyCoDeR is right but I followed a slightly different path though probably with the same results.

/*Container, container body, iframe*/
.mce-tinymce, .mce-container-body, #code_ifr {
    min-height: 100% !important;
}
/*Container body*/
.mce-container-body {
    position: absolute;
    bottom: 0;
    left: 0;
    right: 0;
}
/*Editing area*/
.mce-container-body .mce-edit-area {
    position: absolute;
    top: 69px;
    bottom: 37px;
    left: 0;
    right: 0;
}
/*Footer*/
.mce-tinymce .mce-statusbar {
    position: absolute;
    bottom: 0;
    left: 0;
    right: 0;
}

Revised because TinyMCE changes the id's with menu/toolbar additions or deletions. This works no matter what you do with it.

I'm using pure css solution to achieve this (tinyMCE 4.0.20).

1. Set iframe height to 100%:

   tinymce.init({ height: '100%' })

2. Add styles to auto-resize iframe container:

   .mce-tinymce { height: auto; width: 100%; position: absolute; left: 0; top: 0; bottom: 0; }

   .bq-editor .mce-container-body { height: 100%; }

   .bq-editor .mce-edit-area { position: absolute; top: 57px; bottom: 0; width: 100%; height: auto; }

Note: I have one toolbar line, and top: 57px; in .bq-editor .mce-edit-area is toolbar padding.

Nowadays, you should use the autoresize plugin that comes with tinyMCE. You will have to call tinyMCE like this (jQuery version):

$('.tinymce').tinymce({
  theme : 'advanced',
  plugins : 'autoresize',
  width: '100%',
  height: 400,
  autoresize_min_height: 400,
  autoresize_max_height: 800,
});

I made the experience, that it may be helpful to manually call the resizing in the init_instance_callback to provide the correct height on init. Add this parameter to the passed options, if you need this:

init_instance_callback: function (inst) { inst.execCommand('mceAutoResize'); }

None of the above were working for me in TinyMCE v4, so my solution was to calculate the height based on the toolbars/menu bar/status bar, and then set the height of the editor, taking those heights into consideration.

function resizeEditor(myHeight) {
    window.console.log('resizeEditor');
    myEditor = getEditor();
    if (myEditor) {
        try {
            if (!myHeight) {            
                var targetHeight = window.innerHeight; // Change this to the height of your wrapper element
                var mce_bars_height = 0;
                $('.mce-toolbar, .mce-statusbar, .mce-menubar').each(function(){
                    mce_bars_height += $(this).height();
                });
                window.console.log('mce bars height total: '+mce_bars_height);                          
                myHeight = targetHeight - mce_bars_height - 8;  // the extra 8 is for margin added between the toolbars
            }
            window.console.log('resizeEditor: ', myHeight);
            myEditor.theme.resizeTo('100%', myHeight);  // sets the dimensions of the editable area
        }
        catch (err) {
        }
    }
}

In my case, I wanted the editor window to match the width and height of the actual window, since the editor would come up in a popup. To detect changes and resize, I set this to a callback:

window.onresize = function() {
    resizeEditor();
}

The point is that TinyMCE generates an iframe in the place of the textarea, with this ID: originalID+"_ifr", and a table originalID+"_tbl" for holding the controls and the editor area.

To make fluid width:

document.getElementById(id+'_tbl').style.width='100%'

To make fluid height:

Change dinamically document.getElementById(id+'_ifr').style.height to the height you want, through JS.
This is the script I'm using for this:

function toScreenHeight(id, minus) {
    var height;

    if (typeof(window.innerHeight) == "number") //non-IE
        height = window.innerHeight;
    else if (document.documentElement && document.documentElement.clientHeight) //IE 6+ strict mode
        height = document.documentElement.clientHeight;
    else if (document.body && document.body.clientHeight) //IE 4 compatible / IE quirks mode
        height = document.body.clientHeight;

    document.getElementById(id).style.height = (height - minus) + "px";
}

You can use the code and function calls inside onload and onresize body events.

With version 4 and the option to use flexbox layout in the browser I did the following to get a full width,height editing experience of the parent div.

It should be easy to put the css into a file if you prefer adding it to your existing styles.

var css = '.tinycme-full .mce-edit-area {display:flex;flex-flow:column;} .tinycme-full .mce-edit-area iframe {flex:1 1 auto;}  .tinycme-full {height:100%;} .tinycme-full .mce-tinymce.mce-container { width:100%;height:100%;border:0; } .tinycme-full .mce-panel{border:0} .tinycme-full .mce-container-body.mce-stack-layout {display: flex; flex-flow: column;height: 100%;} .tinycme-full .mce-stack-layout-item{  flex: 0 0 auto;} .tinycme-full .mce-edit-area{flex:1 1 auto;} ',
    head = document.head || document.getElementsByTagName('head')[0],
    style = document.createElement('style');

style.type = 'text/css';
if (style.styleSheet) {
    style.styleSheet["cssText"] = css;
} else {
    style.appendChild(document.createTextNode(css));
}

head.appendChild(style);

The idea is that it make all the needed divs take up as much column space as needed to fill the parent 100% and its done by putting a div around your textarea: <div class="tinycme-full"> <textarea ... /></div>

No jquery or other dependencies are needed andd it now fills the parent 100%.
