Hi! This is a quick tutorial on how to create the letter effect.

I created the letters page on my website to add some real-world mystique to my digital communication. In order to create this vibe, I used CSS (Cascading Style Sheets), HTML (Hyper Text Markup Language), and JavaScript (which is a more dynamic language). If you are unfamiliar with blending these languages take a scroll down here for the full code and an in-depth explanation. I find tutorials such as this one highly helpful, and I used many in creating this code. Check out my favorite resources here. For this page, I used a lot of tutorials from w3schools.com which I highly reccomend for all your HTML, CSS and Java dreams.

overflow: visible;
padding: 0px; }

.envelopeback:hover{
background-image: url('YOUR IMAGE OF THE FRONT'); }

.letter{
display: none; /* this is VITAL! it makes sure you can only read the letter when you open it */
background-image: url('YOUR PAPER TEXTURE');
background-size: 100%;
background-color: white; /* this is just a back up in case the image fails */
width: 460px;
min-height: 640px; /* min means that it will expand beyond that if there is more text */
color: black;
overflow: visible;
border: none;
border-radius: 0px; /* if you don't use rounded corners this won't be important to you*/
position: fixed;
left: 50%;
top: 50%;
transform: translate(-50%, -50%); /* places the letter in the middle of the window when you open it*/
