-- Let's say you have a table full of work:

CREATE TABLE tasks (
       id UUID PRIMARY KEY NOT NULL DEFAULT gen_random_uuid(),
       status TEXT NOT NULL DEFAULT 'pending',
       payload JSON NOT NULL, -- or just have meaningful columns!
       created_at TIMESTAMP NOT NULL DEFAULT NOW()

What forces layout / reflow

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.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

webcss

// utilizes the browser eventsystem
// usefull in cases where you need communication between independent components
// registered events are automatically removed onunload with preserving any other onunload handler
var eventsMixin = function(target) {
	
	var _subscriptions = [];

    target.broadcast = function(type, payload) {
        var ev = new CustomEvent(type, {
            detail: payload,

webcss

/*****************************************
/* DOM touch support module
/*****************************************/
if (!window.CustomEvent) {
    window.CustomEvent = function (event, params) {
        params = params || { bubbles: false, cancelable: false, detail: undefined };
        var evt = document.createEvent('CustomEvent');
        evt.initCustomEvent(event, params.bubbles, params.cancelable, params.detail);
        return evt;
    };
