![]() Line 11 & 12: Calculates the X-offset of that cell & returns the corresponding color.Line 10: Starts a loop to iterate over each column in the row.Lines 7 & 8: Returns the value of the current list item (the list of colors for the row) & calculates its length to determine the number of columns in the row.SASS Lists are index-1 (not index-0), so we subtract 1 from the current index so the 1st row has a Y-offset of 0, 2nd has Y-offset of 1, etc. Line 6: Calculates the Y-offset of all cells in that row. ![]() The $rowIndex will increment by 1 on each loop. Line 5: Starts a loop that iterates X times, where X is the number of rows in our list.Line 3: Returns the number of rows in the list using the built-in length function. ![]() This is the variable the function will modify and return. Line 2: Initializes our $result variable as a string.Line 1: The function takes two arguments: the list of $colors and the $size that the pixels should be.This is what those changes look pixelize ( $colors, $size ) If we make the size of the cat block the final size of our pixel art, we can avoid this problem, but we need the pseudo element to separately define the width/height of our pixels (remember, the size of the shadow is inherited from the element the box-shadow is applied to). Why? Because box-shadow doesn’t take up space, meaning if I were to put another element next to my cat block, it would sit on top of my shadows. Instead of applying the box-shadow to the block itself, I’m going to apply it to a pseudo element instead that is absolutely positioned relative to the block. By utilizing a custom SASS function and lists, we can automate calculating the offset positions and make our code more DRY.įirst, I’m going to make some modifications to our #cat block. I'm also going to use SASS instead of vanilla CSS to avoid writing 414 box-shadow declarations by hand. To help me easily identify the individual pixels, I've used Photoshop to overlay a grid on the reference image.Īlthough you could start drawing your pixel from anywhere, I'm going to start in the uppermost left corner so I don't have to worry about any negative offsets in my box-shadow effects. It is made up of 414 pixels (23 columns x 18 rows). I'm going to be recreating this version of pixel Pusheen. ![]() If you're new to making pixel art, I recommend searching for existing art so you have a reference for where your pixels should be placed. We're going to be creating a pixel version of Pusheen. Now that we know how we can use box-shadow, it's time to start making a real piece of pixel art. By separating our effects with a comma, we can create multiple pixel-looking shadows. Thankfully, the box-shadow property isn't limited to just one effect. It's starting to look like pixel art! But this only gives us two "pixels", and we're going to need a lot more than that. If we change the Y-offset to 0, the result looks like if we had two blocks sitting side-by-side. To move the shadow to the right of the block, we need to set the X-offset to be the same as the width of the block: 20px. Shadows inherit their dimensions from the element they're applied to. We can do this by adjusting the X- & Y-offset parameters according to the rules below. Next, we want to move the shadow so it is beside the block instead of being behind it. How does that help us with creating the straight-edged pixel art? By removing the blur & spread parameters from the box-shadow definition, we can straighten out the sides of the shadow. I prefer to create pixel art with a single, which we can do thanks to the box-shadow property.īox-shadow is commonly used to create a drop shadow effect behind an element, like in the example below. While it is 100% possible to create pixel art by creating a bunch of s and changing their background color, that's a lot of s to keep track of and copy if you want to reuse your pixel in multiple places. This article will show you how using CSS (and a tiny bit of HTML), you can use code to make your own pixel art creations. Before online pixel makers were a thing, I used to spend hours making my own pixel art in Photoshop with the pencil tool. I have always enjoyed looking at and creating pixel art.
