Margin Offset for Anchor Targets with CSS or JavaScript

For sites using a fixed-position “sticky” header or similar, it’s necessary to add an offset margin to any on-page anchor targets. For example this recent article provides a Table of Contents menu with links to each section on the page. Click a link and the page scrolls down to the target element, which is an <h2></h2> heading tag. Thanks to one of the CSS solutions provided in this tutorial, the scrolling takes into account the page’s 50-pixel sticky header, so […] Continue reading »

Vanilla JavaScript: Add Class to Image Links

It seems that for every new web design, I need to add a specific CSS class to linked images. So I can distinguish between regular text links and image links.

WP 6.0 Fix Error: QTags is not defined

“Quick” post about an error that may occur with WordPress 6.0 (and possibly other versions). After updating to WordPress 6, the JavaScript Errors Notifier extension was showing a “QTags is not defined” error on sites where custom Quicktags are configured (via plugins or custom scripts). Because of the error, custom Quicktags were broken and not added to the editor toolbar. This quick post explains why the error is happening and how to fix it (easily). Continue reading »

Replacement for JavaScript Errors Notifier (Chrome Extension)

Heads up about the JavaScript Errors Notifier extension for Google Chrome. Looks like it was removed from the Chrome store sometime last year. Not sure of the reason behind it, but can tell you that currently there are no suitable extensions to replace it. Kinda sucks because JavaScript Errors Notifier was one of my favorite “always on” extensions. It makes it easy to spot any JavaScript errors as you develop, design, or browse the Web. Fortunately there’s still a way […] Continue reading »

Very simple technique, requiring minimal amount of HTML markup and vanilla JavaScript. Continue reading »

Weird Bug with Highlight.js

Working on adding syntax highlighting to my code snippets here at Perishable Press. To do it, I use my free WordPress plugin Prismatic. Basically all the plugin does is load up either the Highlight.js scripts and styles, or it loads up the Prism.js scripts and styles. So I can rule out the plugin itself for this “weird” little bug. The issue is with Highlight.js specifically. Continue reading »

Vanilla JavaScript Smooth Scroll

While working on the site’s 24th redesign, my goal was to simplify the UI as much as possible. As much as I enjoy lots of cool effects, I wanted the new design to be as minimalist as possible. So that meant dropping a LOT of little bells and whistles that were included in the previous design. One feature that didn’t make the cut was smooth scrolling to internal anchor targets. Like when you click a link that takes you #somewhere […] Continue reading »

Basic Webpack Setup

Preparing for Gutenberg, I’ve been sharpening my JavaScript skillz. Getting further into things like Webpack, React, Node.js, and all sort of other awesome scripting adventures.

Even so, the extra tools are good to have in the ’ol developer tool belt, so I’ll be sharing much more about JavaScript stuff […] Continue reading »
