Why would we style checkboxes or radio buttons?<\/h2>\n\n\n\n
To harmonize styles between browsers, for sure, but also to make some of them more effective in precise contexts. One of the most common need (to me) of using CSS on a native checkbox to improve default styling, is to improve accessibility in a \u201ctouch devices context\u201d for the user with no accurate gesture. Tap-able area for checkbox and radio are often so small, too small. And the default border is barely visible on the default checkboxes..<\/p>\n\n\n\n
Also, color contrasts<\/a> on default checkboxes on Mac for instance, are really poor. I can’t even understand why it is so badly designed. That’s why I consider this cool checkbox also a good way to improve user experience.<\/p>\n\n\n\n Maybe your goal is elsewhere, so I’m not gonna go deeper into the reasons, let’s jump into my technical solution.<\/p>\n\n\n\n With this example, we will write a solid code base for our CSS. It will give me the possibility to explain how selectors are working with these simple checkboxes. As you can see, these are simple checkboxes, without complex layout: a colored border, a check icon and even some focus styles I’m going to detail in the code.<\/p>\n\n\n\n See the demo<\/a><\/p>\n\n\n\n Let’s start with the HTML code. A simply composed code with one You have now in the order 4 checkboxes: 1 empty, 1 checked and 1 disabled and 1 disabled checked. For the focus styles, you’ll need to use the tab key will testing the page, but let’s style it before that.<\/p>\n\n\n\n Please be careful with the Note that the code doesn’t use The It’s precisely in those selectors that you will find the magic: It’ll display custom checkbox with my recent browser, and classical ones with my old browser. If you don’t need to support old browser (below IE11), you can use a easier to write code.<\/p>\n\n\n As you can see, the selectors are simpler, I removed all the A bit of explanation in the code itself: The first declaration<\/strong> allows you to place the checkbox under the upcoming custom checkbox to hide it visually without using All our custom styles will use this type of selector: If you don’t have to support IE below version 11, use the second syntax I provided just above.<\/p>\n\n\n\n Now, we will visually create the checkboxes thanks to The first two declarations are for the box and the check symbol aspects (size, color, etc). The two next define the states: not-checked or checked. An animation is played because of the We need the checkbox label to make use of our pseudo – elements because Basics done, now we will set the other status: disabled, disabled checked, focused). Find below some styling ideas, but feel free to edit them.<\/p>\n\n\n That’s all for these custom styles.<\/p>\n\n\n\n Don’t forget to use vendor prefix with some of the CSS3 properties if you still need to support those.<\/p>\n\n\n\n As you can see, I didn’t use icon fonts here, but if yo already use one on your site, use the decorative icon that correspond to your style. And with this CSS and HTML code, we made the checkbox accessible. Pretty neat for a fake checkbox isn’t it? It’s even compatible with touch devices and assistive technology.<\/p>\n\n\n\n I will not explain everything about this demonstration, the idea is exactly the same. You can now compose a more complex HTML code using Here another idea of what you can do with this code, with this accessible switch demonstration.<\/p>\n\n\n <\/p>\n\n\n\n See the demo<\/a><\/p>\n\n\n\n These two demonstrations are using respectively We didn’t use background images for obvious quality and accessibility reasons, but you could replace this idea of background images with SVG icon, like this demo that uses an smooth ease animation.<\/p>\n\n\n\n Hey! Now you got the idea and this example of code with checkboxes, I’m sure you can handle it with radio buttons or toggle switches. I won’t go into the code, but if you need any advice, jump into the comments section or reach me on Twitter<\/a>. I’ll help you \ud83d\ude0a<\/p>\n\n\n\n Now you can do what you want with checkboxes (or radio), find below so inspiration to go further.<\/p>\n\n\nSlightly modify the checkbox design<\/h2>\n\n\n\n

Same for the focus styles, you can adjust the interaction effect using a different focus outline, or dotted borders or any style that would match your identity. If the border is too complex to style, you can use the outline property (which will soon respect the border radius, good for your radio fields too).<\/p>\n\n\n\nWith CSS Design Checkbox that are more advanced<\/h3>\n\n\n\n
