The following function retrieves three data items from local storage, then uses them to set custom styles on a page.
function setStyles() {
var currentColor = localStorage.getItem('bgcolor');
var currentFont = localStorage.getItem('font');
var currentImage = localStorage.getItem('image');
document.getElementById('bgcolor').value = currentColor;
document.getElementById('font').value = currentFont;
document.getElementById('image').value = currentImage;
htmlElem.style.backgroundColor = '#' + currentColor;
pElem.style.fontFamily = currentFont;
imgElem.setAttribute('src', currentImage);
}
