These snippets are my attempt to save and organize various bits of code, best practices, and resources relating to web development and design. They also function as a to do list of sorts, for things I want to implement in my own code, but haven't yet. The concept is inspired by Jeremy Keith's links and CSS-Tricks, among other things. Enjoy.
Copying text to the clipboard shouldn't be hard. It shouldn't require dozens of steps to configure or hundreds of KBs to load. But most of all, it shouldn't depend on Flash or any bloated framework.
That's why clipboard.js exists.
The box alignment specification details how items are aligned in the various layout methods. As different layout methods pose different constraints in terms of alignment, some of the behaviour of Box Alignment is layout method dependent. This cheatsheet compares alignment in CSS Grid Layout and Flexbox.
This example of using background sync looks like it’s specific to Twilio, but the breakdown of steps is broad enough to apply to many situations:
On the page we need to:
- Register a Service Worker
- Intercept the “submit” event for our message form
- Place the message details into IndexedDB, an in browser database
- Register the Service Worker to receive a “sync” event
Then, in the Service Worker we need to:
- Listen for sync events
- When a sync event is received, retrieve the messages from IndexedDB
- For each message, send a request to our server to send the message
- If the message is sent successfully, then remove the message from IndexedDB
And that’s it.
When a browser receives the HTML response for a page from the server, there are a lot of steps to be taken before pixels are drawn on the screen. This sequence the browsers needs to run through for the initial paint of the page is called the "Critical Rendering Path".
Knowledge of the CRP is incredibly useful for understanding how a site's performance can be improved. There are 6 stages to the CRP -
- Constructing the DOM Tree
- Constructing the CSSOM Tree
- Creating the Render Tree
- Generating the Layout
This is really excellent: take a JPG, which has great compression for photos, but doesn't support transparency, and link it within an
<svg> which can apply a clipping mask based on a path. The path can be traced manually over the photo in Photoshop or Illustrator, and can be exported as an SVG file from Illustrator. The following code (minus the path data), demonstrates how to do this:
<svg viewBox="0 0 921.17 1409.71"> <defs> <clipPath id="chris-clip"> <path d=" ... " /> </clipPath> </defs> <image xlink:href="/images/chris.jpg" clip-path="url(#chris-clip)" x="0" y="0" width="921" height="1409"> <svg>
Do you remember how the web used to work? How the web was supposed to work?
In the earlier days of the web, we always published to our own web site. If you weren’t happy with your web host, or they went out of business, you could move your files and your domain name, and nothing would break.
Today, most writing instead goes into a small number of centralized social networking sites, where you can’t move your content, advertisements and fake news are everywhere, and if one of these sites fails, your content disappears from the internet. Too many sites have gone away and taken our posts and photos with them.
I want to encourage more independent writing. To do that, we need better tools that embrace microblogs and the advantages of the open web. We need to learn from the success and user experience of social networking, but applied to the full scope of the web.
This looks like an excellent resource for anyone wanting to start building websites.
