I need to set the size of content editable div same as the text inside it
.Please see this js fiddle https://jsfiddle.net/felixtm/jaboLc3u/7/
$(".new-div").css("width",'auto');
} ,
stop: function() {
$(".new-div").css("width",'auto');
}
});
$(document).on("click",".closeButton",function(){
$(this).closest('div').remove();
});
$(".new-div").on("click", function(){
var uscontent= $(".new-div").text();
if(uscontent.trim()==="message"){
$(".new-div").text('');
} });
$("#font-size").on("change",function(){
var v=$(this).val();
$('.new-div').css('font-size', v + 'px');
});
$('.resizeButton').draggable({
containment: '#bord',
drag: function() {
$('.new-div').height($('.resizeButton').position().top + 17);
$('.new-div').width($('.resizeButton').position().left + 17);
$('.new-div').width($('.resizeButton').position().left + 17);
$('.new-div').css({ 'font-size': ($('.new-div').height() / 2.3)});
}
})
.new-div {
z-index: 1; position: absolute; width: auto; word-break: break-all; text-align: center; left: 0px; right: 0px; top: 15px; border:2px solid black;}
.parent-div {
max-width: 236px; width: 236px; position: relative; overflow: hidden; }
.closeButton
{
display:block;
position:absolute;
top:-10px;
left:-10px;
width:27px;
height:27px;
background:url('http://cdn-sg1.pgimgs.com/images/pg/close-button.png') no-repeat center center;

Here first loading the size of content editable div and text inside is correct . But when i try to resize the div then there is a gap coming between the text and border of the div .

Some time this problem is also coming http://www.awesomescreenshot.com/image/1753603/d27436262d454bee88bf53ebfab2049a
I tried display:inline-block; but it is not working .
How to solve this ?

This will solve your font-size problem, this is trickier than it seems.

Do you mean padding of resizable div? https://jsfiddle.net/bimbonkens/2mpjkxad/
padding: 0;
