its really easy use this code first add another id or class for your button because by choosing btn btn-danger all btn btn-danger buttons will get hidden
for example if you add id "loadmore" your code will be something like this
<button href="#" id="loadmore" class="btn btn-danger" onclick="$('#target').toggle();">
<b><font size="6">LOAD MORE</font></b>
</button>
<script>
$('#loadmore').click(function(){
////// code to show more
$('#loadmore').hide(); //// u can use other functions too
});
</script>
any way i recommend you to use the code bellow (its clearer)
<style>
button#loadmore{
font-size: 60px;
font-style: bold;
}
</style>
<script>
$(document).ready(function(){
$('#loadmore').click(function(){
$('#target').toggle();
$('#loadmore').hide(); //// u can use other functions too
});
});
</script>
<button href="#" id="loadmore" class="btn btn-danger"> LOAD MORE </button>
