Recently I came across a CodePen demo by a developer/engineer named Jane that was Tweeted out by Šime Vidas. The demo has a neat collection of HTML and CSS tricks rolled into one that I thought was worth examining in detail.
When I visit a page, I get annoyed when I try to interact with elements while the website is still loading. Often stuff is moving around, fonts aren’t quite loaded, and it feels broken.
I know nowadays we’re obsessed in this industry with gaining every millisecond in page performance. But in a couple of projects that I recently overhauled, I added a subtle and clean loading mechanism that I think makes the experience nicer, even if it does ultimately slightly delay the time that the user is able to start interacting with my page.
This week I did some research to try to build a hamburger menu that opens a slide-out navigation panel, a common design pattern nowadays. But I wanted to ensure the whole thing was keyboard-friendly and as accessible as possible.
I’m not 100% sure what I’ve come up with is the most accessible solution, but I did consult a number of decent sources on building accessible navigation menus like these. I also did some rudimentary testing using the free NVDA screen reader, to ensure there are no major problems.
I’ve been coding websites for a long time but even I was a little puzzled when I came across a Hacker News comment where the commenter described their own makeshift CMS that involves using your own file system. The most interesting part to me was when the person said they add CSS to pages on their personal projects by means of HTTP headers.
I had heard of this technique before and the person does say in the comment that this doesn’t work in every browser. But I decided to do some research to figure out how one might do this and why this would be easier than just dropping in one or more <link> elements in the HTML.
There’s an interesting DOM feature that I just came across that’s a method of the document object that allows you to remove elements from an <iframe> that’s embedded on a page and drop them into the current page (or vice versa).
In other words, you adopt the elements from the child frame into the parent. The code for document.adoptNode() looks like this:
In response, a couple of other developers released a Google doc that explains why you should not be too quick to drop jQuery without careful consideration of all the problems it overcomes.
In this post, based on some instructions in that Google doc, I’ll describe how you can examine the DOM bugs and incompatibilities that jQuery attempts to address.
But even if you already have a basic understanding of what JSON is and have used it in some of your projects, there might be a few things you weren’t aware of. So in this JSON tutorial and guide, I’m attempting to provide a fairly comprehensive discussion of JSON, its history, and its usefulness. I’ll close with a list of some practical JSON tools that might come in handy in future projects.
