Principle makes it easy to design animated and interactive user interfaces. Whether you're designing the flow of a multi-screen app, or new interactions and animations, Principle lets you create designs that look and feel amazing.

Change the way you design with the most powerful prototyping platform on the planet.

Lightbox, modal window, dialog, overlay… There are many names used to describe a component with the same (or very similar) functionality. For the purpose of this article, I will use these terms interchangeably to refer to a window which is triggered by the user, appears on top of the viewed page overlaying other content, and which must be acknowledged by the user before they can come back to the main page area. When the window is open, the rest of the page is dimmed and the user is only able to interact with that window's content.

We believe... in a web accessible to everyone. Tenon.io exists because universal design is hard. We create software to help you reach beyond compliance and build superior experiences for everyone.

The practical guide to why laying out type never quite does what you want

Narrator is the integrated screen reader for Windows 10. The August 2nd Windows 10 Anniversary update introduces several new Narrator features, including a Narrator mode designed specifically for web developers.

Svgsus cleans the svg and writes the code for you. Drag, paste or import an entire set for a rapid workflow.

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.

Design hand-off has never been easier. Generate styleguides and resources, automatically.

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."

Forms. Without them, the web would not be what it is today, but they are challenging from a markup and styling standpoint.

In this session, we will explore forms from top to bottom, examining how they work and how their components can be incorporated with other elements to maximize accessibility, improve semantics, and allow for more flexible styling. You’ll get to see the complete picture with forms, including

• new HTML5 field types;
• validation, error messages & formatting hints;
• how to mark up and style forms for the greatest flexibility in responsive designs; and
• best practices for enhancing forms with JavaScript.

SVG1.1 accessibility support is limited in browsers and screen readers. Things are set to improve with SVG2, but ARIA can be used now to improve the accessibility of simple SVG.

The issues of this pattern are now widely recognized, but what’s the real solution?

Some practical ARIA examples to enhance your application accessibility (by @heydonworks).

"- А у вас есть некий набор стилистических паттернов? Например: предложить клиенту 20 вариантов обоев для сайта.

• Нет. Мы стараемся давать один вариант дизайна."
