How to make a div have a fixed size?

Question

I made a webpage, on which clicking the button 30px changes the font inside the div.

I have a ul inside it with the buttons. When I change the font size, the div expands and the nav buttons move with it as well.

How do I make it so it stays fixed but the fonts can still change.

Answer 1

Try the following css:

#innerbox
{
   width:250px; /* or whatever width you want. */
   max-width:250px; /* or whatever width you want. */
   display: inline-block;
}

This makes the div take as little space as possible, and its width is defined by the css.

Expanded answer

To make the buttons fixed widths do the following :

#innerbox input
{
   width:150px; /* or whatever width you want. */
   max-width:150px; /* or whatever width you want. */
}

However, you should be aware that as the size of the text changes, so does the space needed to display it. As such, it's natural that the containers need to expand. You should perhaps review what you are trying to do; and maybe have some predefined classes that you alter on the fly using javascript to ensure the content placement is perfect.

This worked for the div that changes the font but now my stupid buttons are still floating :S – Balsamiferous

@MikeCollins I have expanded my answer. Altering the size of the text will make the text flow out of the buttons if they are fixed width - some browsers may still expand them. I think you need to rethink your strategy for what you are trying to achieve. – Count

ok, but if I don't know what width I want? I want to remain fix width after first render – Duenas

@Duenas that is beyond the scope of the original question. Please open a new question as what you are aiming to do differs from the OP. – Count

Answer 2

you can give it a max-height and max-width in your .css

.fontpixel{
  max-width:200px; 
  max-height:200px;
}

in addition to your height and width properties

Okay so it works but now the buttons move all over is there a way to make it stay in its spot? – Balsamiferous

Answer 3

Thats the natural behavior of the buttons. You could try putting a max-width/max-height on the parent container, but I'm not sure if that would do it.

max-width:something px;
max-height:something px;

The other option would be to use the devlopr tools and see if you can remove the natural padding.

padding: 0;

<div>
  <img src="whatever it is" class="image-crop">
</div>

 /*mobile code*/
    .image-crop{
      width:100%;
      max-height: auto;
     }
    /*desktop code*/

  @media screen and (min-width: 640px) {
    .image-crop{
       width:100%;
       max-height: 140px;
      }

     style="height:100px;
     width:55%;

     cursor:pointer">
</div>

Answer 6

<div class="ai">a b c d e f</div> // something like ~100px
<div class="ai">a b c d e</div> // ~80
<div class="ai">a b c d</div> // ~60 

<script>

function _reWidthAll_div(classname) {

var _maxwidth = 0;

    $(classname).each(function(){

    var _width = $(this).width();

    _maxwidth = (_width >= _maxwidth) ? _width : _maxwidth; // define max width
    });    

$(classname).width(_maxwidth); // return all div same width

}

_reWidthAll_div('.ai');

</script>
