Incrase / decrase div size with 1 px on click button
<p>I've made a website with windows PVC and doors PVC products.
I want to make order page with a calculator. it's working but I need now to animate the configuration of the window.( example: <a href="http://orasvirtual.ro/images/a.JPG" rel="nofollow">http://orasvirtual.ro/images/a.JPG</a>)
so, the default window size is 250px height and 350px width. I made 4 buttons:
(example: <a href="http://orasvirtual.ro/images/b.JPG" rel="nofollow">http://orasvirtual.ro/images/b.JPG</a>)
increase height, decrease height, increase width and decrease width. 
I've made this until now, but how to make to increase/decrease holding the click for x seconds.</p>

<p>thanks for all</p>

<p>ok, until now I've made this, thanks to NullPointer: </p>

<p>html:</p>

<pre><code>&lt;div  id='divid'&gt;div&lt;/div&gt;
&lt;button id="inch" &gt;+ h&lt;/button&gt;
&lt;button id="dech" &gt;- h&lt;/button&gt;
&lt;button id="incw" &gt;+ w&lt;/button&gt;
&lt;button id="decw" &gt;- w&lt;/button&gt;
</code></pre>

<p>jquery:</p>

<pre><code>$("#inch").click(function(){

var height = $("#divid").height()+1; //to decrease just -1 instead of 1

$("#divid").height( height );
})
$("#dech").click(function(){

var height = $("#divid").height()-1; //to decrease just -1 instead of 1

$("#divid").height( height );
})
$("#incw").click(function(){

var width= $("#divid").width()+1; //to decrease just -1 instead of 1

$("#divid").width( width );
})
$("#decw").click(function(){

var width= $("#divid").width()-1; //to decrease just -1 instead of 1

$("#divid").width( width );
}) 
</code></pre>
