Typography is an important part of web design nowadays and free services like Google Web Fonts or Adobe’s Typekit make custom fonts on the web a commodity.

Let’s take it slow and start with a core principle of typography, vertical rhythm. Vertical rhythm is about spacing body text or, more generally, vertical stacked elements, in a consistent manner to give structure and hierarchy to your content.

Some use the body text’s line-height as the measuring unit for the vertical rhythm. But using half of this value is a better choice because it can give you more reliability on automatic calculation of line-height for different font sizes using mixins.

The easiest-to-use graphical effects are the shorthand filter functions. You apply them with the CSS filter property. The browser manipulates the appearance of the corresponding element before painting it to the page. Filter functions are supported prefix-free in Firefox since version 35 (stable release in January 2015). They have been supported with the -webkit- prefix in Safari, Chrome, and Blink-based Opera for a few years now.

Those colorful filters uses css blend modes and were heavily inspired by Spotify new 2015 ads.

This technic is called "DuoTone", and today, with the power of CSS we can play around with some blend-modes properties, to get some cool visual results.

The redesign of my website finally gave me an opportunity to experiment with SVG filters and color manipulation. The duotone look, which was made sort of trendy again earlier this year by Spotify's new brand identity, is based around manipulating the image's color range by modifying the individual color channels.

"The HTML of a modern app is mostly a div soup. CSS by itself does not offer any structured model at all. High-level JavaScript components use abstractions that are not consistently tied to styles or markup. At the UX level, interfaces are described in terms that have nothing in common with technical implementations. Enter BEM, a unified semantic model for markup, styles, code and UX. "
"Not all blocks have elements."
"One DOM node may host several blocks. A node may be an element within one block and (at the same time) a container for another block."
"Once the designer is familiar with BEM’s terms, they can iterate towards designing blocks and elements, instead of “screens.” This will also help them to identify similar UI parts and unify them."

There are too few things not to like about SVG, and I don’t mean the things that browsers cause by incomplete or lack of certain features or buggy implementations. via Pocket

Icons! We see them all over the web, and they're essential to most pattern libraries and web design systems. I recently needed to implement such a system. It had to be non-prescriptive, scalable, and dynamically editable via CSS. The icons were to be used by multiple teams in many different applications, built with various frameworks and techniques. They needed to have the ability to be restyled, get cached, and be updated quickly and easily as more icons are added. Basically, the icon system needed to be really, really flexible. Challenge accepted.

px-em is a px to em tool which allows you to work out the em sizes from px. Just add the parent px size in the top box, required size in the bottom and you're done!

Interestingly I found that there are two actions taken by the browser: firstly on the percentage itself - for example - Internet Explorer 7-11 will truncate any percentage to 2 decimal places, more modern browsers will round to a large number of decimal places.

Lint: Bad practices of CSS with explanations

This article is to serve as a guide for best practices when using icon fonts on the web. Because icon fonts are still in their infancy, browser support and new technologies are constantly being developed. Be sure to check back often for updated information.

Anybody who’s followed me or my work for any length of time will no doubt know that I’m a huge proponent of the BEM naming convention. What I’m about to talk about in this post is not an alternative or different naming convention to BEM, but an augmentation: small additions that level BEM up a notch. This extended BEM syntax has been dubbed BEMIT, as it borrows some paradigms and patterns from the (as yet unpublished) Inverted Triangle CSS architecture. BEM + ITCSS = BEMIT.
