Help in adding cookies to the Hide/Show sidebar.

Hi everyone,

I obtain a code to create a collapsible sidebar for my website layout from here: https://www.depiction.net/?id=csssidebar

I have successfully implemented it but I would like to add cookies to it so that it can remember the state. I tried my best but due to my limited knowledge in programming, I could not figure out how to do it.

Would be grateful if anyone can assist:

<script type=”text/javascript”>
<!–

// begin function.
function toggle() {

// Initialize our object data from our XHTML divs.
var bar = document.getElementById(‘sidebar’);
var barText = document.getElementById(‘sbText’);
var box = document.getElementById(‘content’);

// If the sidebar is expanded…
if (bar.style.width == ‘250px’) {

// Collapse it by setting its width to 15px
bar.style.width = ’15px’;

// Hide the sbText div so that its text isn’t visible or
// repositioned.
barText.style.display = ‘none’;

// Resize the content div to its new, expanded width.
box.style.width = ‘720px’;

// Otherwise, if the sidebar is already collapsed…
} else {

// Restore the width of the sidebar.
bar.style.width = ‘250px’;

// Make the sbText div visible again.
barText.style.display = ‘block’;

// Set the content div width back to original size.
box.style.width = ‘500px’;
}
}

// –>
</script>

Thanks in advance!
