HTML popover Attribute

15.4.2024
Modals have been an important part of websites for two decades. Stacking contents and using fetch to accomplish tasks are a great way to improve UX on both desktop and mobile. Unfortunately most developers don’t know that the HTML and JavaScript specs have implemented a native modal system...

How to Override width and height HTML attributes with CSS

One of the HTML elements that frequently comes into collision with CSS is the img element. As we learned in Request Metrics’ Fixing Cumulative Layout Shift Problems on DavidWalshBlog article, providing image dimensions within the image tag will help to improve your website’s score....

Customizing HTML Form Validation

9.1.2023
Form validation has always been my least favorite part of web development. You need to duplicate validation on both client and server sides, handle loads of events, and worry about form element styling. To aid form validation, the HTML spec added some new form attributes like required and pattern...

Legacy String Methods for Generating HTML

26.4.2022
I’m always really excited to see new methods on JavaScript primitives. These additions are acknowledgement that the language needs to evolve and that we’re doing exciting new things. That being said, I somehow just discovered some legacy String methods that you probably shouldn’t...

Test Your Site With Real Users

2.12.2021
A few years ago, there was this French book publisher. They specialize in technical books and published an author who wrote a book about CSS3, HTML5 and jQuery. The final version, however, a glaring typo on the cover where “HTML5” …

Creating Colorful, Smart Shadows

4.5.2021
A bona fide CSS trick from Kirupa Chinnathambi here. To match a colored shadow with the colors in the background-image of an element, you inherit the background in a pseudo-element, kick it behind the original, then blur and filter it. … The post Creating Colorful, Smart Shadows appeared...

Happier HTML5 form validation in Vue

3.12.2020
It’s kind of neat that we can do input:invalid {} in CSS to style an input when it’s in an invalid state. Yet, used exactly like that, the UX is pretty bad. Say you have <input type="text" required>. That’s immediately invalid before the user has done anything....

Lazy Load IFRAMEs

13.7.2020
We’ve known for a decade that lazy loading resources like JavaScript, CSS, and especially images is a massive performance win for web pages. At first we used tricks and JavaScript to do the lazy loading, but more recently native image lazy loading has debuted in browsers. Did you know that...

JavaScript Picture-in-Picture API

14.4.2020
As a huge fan of media on the web, I’m always excited about enhancements to how we can control our media. Maybe I get excited about simple things like the <video> tag and its associated elements and attributes because media on the web started with custom codecs, browser extensions,...

Custom Elements v praxi

29.3.2020
Jak se něco dozvědět o nové technologii? Vyzkoušet ji v praxi! Mám za sebou už pár neseriózních pokusů s vlastními HTML značkami a v minulých dnech a týdnech jsem s jejich pomocí přepsal regulérní aplikaci webového klienta pro MPD, nazvaného CYP. Co jsem se při tom naučil a dozvěděl?

Value Bubbles for Range Inputs

26.3.2020
HTML5 range inputs, in supported browsers and by design, don't show the user the actual value they are submitting. If you want to use the cool slider, but show the value, you'll have to do that yourself. Here we use the output element and jQuery to show the current value in a bubble that hovers...

Fluid Width Video

IN A WORLD of responsive and fluid layouts on the web, ONE MEDIA TYPE stands in the way of perfect harmony: video. There are lots of ways in which video can be displayed on your site. You might be self-hosting the video and presenting it via the HTML5 <video tag. You might...

Multi-Thumb Sliders: Particular Two-Thumb Case

7.1.2020
This is a concept I first came across a few years back when Lea Verou wrote an article on it. Multi-range sliders have sadly been removed from the spec since, but something else that has happened in the meanwhile is that CSS got better — and so have I, so I recently decided to make my...

Is Web Design Easier or Harder Than it was 10 Years Ago?

20.12.2019
Is it harder or easier to build a website now than 10 years ago? Has the bar gone up or down? I don't have any data for you, but I can shell out some loosey-goosey opinions. HTML HTML5 was the only big HTML change in the last decade, and it wasn't particularly dramatic. It's cool it's the looser...

Quick Gulp Cache Busting

7.8.2019
You should for sure be setting far-out cache headers on your assets like CSS and JavaScript (and images and fonts and whatever else). That tells the browser "hang on to this file basically forever." That way, when navigating from page to page on a site — or revisiting it, or refreshing...
