![]() We’ll use that in the CSS, which is going to look like this: /* The parent element */ Lastly, note that we have an inlined custom property on the parent element that we’re calling -widget-size. Why are we using a separate div instead of putting the class and attribute on the list items themselves? It’ll help us later when we get to drawing lines. Secondly, notice that we’re storing the values in a data attribute we’re calling data-value that’s contained in its own div inside a list item in the unordered list. First is that we’re wrapping everything in a element, which is a nice semantic HTML way of saying this is self-contained content, which also provides us the optional benefit of using a, should we need it. Here’s our HTML: Ī couple notes to glean here. Let’s create an unordered list to hold our data points and apply some styles to it. Let’s say we have an array of data to display points on an X and Y coordinate system, where days of the week fall along the X-axis and the numeric values represent points on the Y-axis. If you break the process down like that, you can recreate any basic line chart in CSS. If you are creating a line chart by hand (as in, literally drawing lines on a piece of graph paper), you would start by creating the points, then connecting those points to make the lines. If that didn’t scare you off, then roll up your shirt sleeves, and let’s get started!ĬodePen Embed Fallback Let’s start with the baseline You can make everything you need with just CSS and a couple of custom properties in your HTML. Well, there is a way! If all you need is a simple line chart, there’s no need to load in a huge JavaScript library or even reach for SVG. While CSS can “draw lines” with borders and the like, there is no clear method for drawing a line from one point to another on an X and Y coordinate plane. There are plenty of articles out there for creating CSS-only bar charts, column charts, and pie charts, but if you just want a basic line chart, you’re out of luck. Sure, you can use SVG or a JavaScript chart library like Chart.js or a complex tool like D3 to create those charts, but what if you don’t want to load yet another library into your already performance-challenged website? If you know, then comment below.Line, bar, and pie charts are the bread and butter of dashboards and are the basic components of any data visualization toolkit. For example the steering wheel of this racing car is actually a letter - a “Right Semidirect Product” (don’t ask me what this letter is used for. This adds a line break.Īnother way of using letters as a mean to design is using certain symbols. In order to position it horizontally you can use \A. I use this to position the letters vertically. The \000a0 stands for non-breaking space. For the antenna of the Android, I added a "\000a0V” in the content value of one of the pseudo-elements. I don’t know why people don’t use it but I use it quite a lot. It’s a technique I seldom see in other drawings. For this you need a little bit creativity. If you inspect the code of the Android careful enough, you’ll see that it is drawn with all the techniques I explained here so far. By simply changing the background-size I could create 2 replica of the background-image. The eyes of the Android is just one circle drawn with radial-gradient. If end point of one color is the same as the start point of the next color, you create the illusion of a hard edged line: div As you can see, you can create hard edged lines by end of a color to the same position as the next color. Next I would add vertical lines to achieve the illusion of barcodes. In this article, however, I’ll reveal to you in easy and simple to understands words the secrets of how you can draw an image with pure CSS and only one single DIV. But their articles focus on multiple DIVs. Totally worth reading! Check them out if you have time. There are other articles already about how to create CSS art. The image of a MacBook Pro with the glossy screen and reflections of the chassis below is, for example, drawn with only one DIV and pure CSS only. I also have a small collection of single DIV CSS art myself. Only CSS and a single DIV - the minimum amount of HTML needed to draw an image with CSS. It’s even more impressive once you know that these quite complex and detailed clipart-like images were drawn with only a single DIV and pure CSS, meaning no preprocessor like SASS/SCSS, no images, no SVG. On her website she presented her contribution to #divtober. Recently #divtober, a hashtag initiated by Lynn Fisher, ended - at least for 2020. Secrets of drawing with CSS and a single DIV
