Weekly Platform News: CSS ::marker pseudo-element, pre-rendering web components, adding Webmention to your site

?ime's weekly web platform news delivers insightful updates for developers. This week's highlights include keyboard accessibility issues with date pickers, a new web component compiler tackling FOUC, styling list item markers with CSS, and a straightforward guide to adding Webmentions.

Date Input Accessibility Concerns

Standard text fields are preferred by keyboard users over complex date pickers; screen reader users also experience challenges with native date controls. Plain text inputs with custom validation offer a more accessible solution.

Prioritizing plain text inputs for dates, with client-side and server-side validation, has proven effective, especially for known dates like birthdays.

Streamlining Web Components with Stencil

Stencil, a web component compiler, pre-renders components (including Shadow DOM) or delays rendering until styling is complete, preventing FOUC (Flash of Unstyled Content). It optimizes polyfill loading and provides a developer-friendly Component API with helpful decorators and hooks.

import { Component, Prop, h } from "@stencil/core";

@Component({
  tag: "my-component"
})
export class MyComponent {
  @Prop() age: number = 0;

  render() {
    return <div>I am {this.age} years old</div>;
  }
}

Styling List Item Markers with CSS ::marker

The ::marker pseudo-element allows styling of list item markers (bullets, numbers) when display: list-item is used. Currently, Firefox is the primary browser with full support.

Implementing Webmentions in Four Steps

Adding Webmentions to your site enhances engagement and interaction:

  1. Register: Create an account on Webmention.io (a webmention receiving service).
  2. Add Link Tag: Include <link rel="webmention" href="%5Byour-webmention-endpoint%5D"> in your HTML. CMS plugins are also available.
  3. Fetch Webmentions: Use Ajax to retrieve webmentions from Webmention.io for display.
  4. Automate Sending: Employ webmention.app to automate sending webmentions when publishing content with links to other Webmention-enabled sites.

What is 'render-blocking CSS'? What is 'render-blocking CSS'? Jun 24, 2025 am 12:42 AM

CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

CSS: When Does Case Matter (and When Doesn't)? CSS: When Does Case Matter (and When Doesn't)? Jun 19, 2025 am 12:27 AM

In CSS, selector and attribute names are case-sensitive, while values, named colors, URLs, and custom attributes are case-sensitive. 1. The selector and attribute names are case-insensitive, such as background-color and background-Color are the same. 2. The hexadecimal color in the value is case-sensitive, but the named color is case-sensitive, such as red and Red is invalid. 3. URLs are case sensitive and may cause file loading problems. 4. Custom properties (variables) are case sensitive, and you need to pay attention to the consistency of case when using them.
