Everything has moved to the left of the page... :( - ☔︎ ∙ I need Help!

It was fine, I was editing graphics. Now it isn't fine! I'm not sure what's up, I tried to look at it myself and I also went to the last draft but somehow, I messed that up too! So I don't have a previous draft to undo the damage. Would some kind soul help me look over my code?

<h2>A Page for my Fandoms</h2>
<p>I've been a part of fandom since I was a little-little kid. I was around 6 googling pictures of characters I liked from shows and movies, and I found art of it by accident. (On... deviantart- shudder!!! <img src="graphics/fudan/yeesh.gif"><img>) I was around 8 when I started making my own accounts on stuff, and then my fandom life took off lol... I've been a little infamous (and famous-ish) on various websites throughout my life, many of them now defunct. I read a lot when I was younger, wrote a lot of fanfic. Quizilla was my jam!</p>
<p>Maybe you read one of my many mid-puberty, hormone-driven fanfics, or saw some of my fanart or OCs that I thought were SO GOOD, or argued with me under stamps or in the depths of Yahoo Answers- where I was top contributor on a regular basis at the wise old age of 11. So that probably tells you about the quality of the spaces I spent time in... <img src="graphics/fudan/nopls.gif"><img> </p>

<div class="main">
<p>You can have as many of these boxes as you want. They'll be nested inside your "Big Container" div if you keep the code like this, but if you take them out of that div, they'll arrange themselves instead of being constrained by the box. "Container," "Small Container" and "Big Container" divs can all have background colors and borders assigned to them if you want, but in this version of the code, they are transparent. </p>
<p>To change the colors of various elements, you can replace the "white" and "black" color tags with other color names or with hex codes. To add a background image, replace "link" in the background image code with an actual link. To change your font, upload a font file to Neocities and set it as the src link for the font. You can name the font family whatever you want then. Alternately, you can remove the src link and use the name of a web font (you can look up the names of these).</p>
<p>I left my custom cursor code in here at the top. In order to get rid of the custom cursor, just delete that section of code. In order to replace it with a different custom cursor, go to Cursors-4U and copy the code for your desired custom cursor, then replace it. Cursor animation doesn't work outside Internet Explorer as far as I can tell, so pick one that looks fine not animated.<p>
<p>You can make more styles of div if you like - as many as you want! This is good if you want lots of different elements on your page, but it can gum up your code somewhat.</p>
