| WebSockets vs. Server-Sent events/EventSource | |
| --------------------------------------------- | |
| Both WebSockets and Server-Sent Events are capable of pushing data to browsers. To me they seem to be competing technologies. | |
| What is the difference between them? When would you choose one over the other? | |
| Websockets and SSE (Server Sent Events) are both capable of pushing data to browsers, however they are not competing technologies. | |
| Websockets connections can both send data to the browser and receive data from the browser. | |
| A good example of an application that could use websockets is a chat application. |
All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.
Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.
elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent
CSS Modules lets you write and use simple class names rather than remembering and maintaining long unique class names for every component. CSS Modules mutates all of your classnames from each partials into new, completely unique classnames that will not conflict when they are bundled together into your main CSS file. Then, a JSON file is generated that maps the happy classnames from each file to the unique classname in the combined file. You load this map in PHP, and begin using the easy-to-remember classnames as you wish.

I like (love ?) Keynote because it
If I could remove that last argument, I would, but the fact is that, as a consultant, the final document is almost always expected to be a powerpoint document. Don't ask me why, it is just so. I am fighting against it but I did not win the battle so far ...
