PUBLIC MARKS from decembre with tag css

The recipe for the best user experience: Start with POSH, a simple set of heading/div pairs Add ARIA (role, aria-selected, aria-hidden, aria-labelledby) and tabindex attributes using JavaScript as these would be confusing if there was no behavior attached to the widgets. Use JavaScript to also plug a class on the component according to its type (accordion or tabpanel). Style the widget using the selector inserted by the script, this way containers are not hidden if there is no script support. Use cursor to style the tabs because those behave like buttons (default), not links (pointer). In case the component is displayed as a Tab Panel, style it as an Accordion before its tabs start wrapping (to accomodate user’s font-size) or at narrow widths...... ../..

SVG is gaining popularity in web design these days and you can use tools like Illustrator or Inkscape to create SVG graphics. But when it comes to web design, we should always optimize for lighter results. Here the 20 tools that you can use to work with SVG quickly and efficiently. We have mostly online tools, that can help in optimization, conversion, making patterns, and more.

You can perform a wide variety of designs, art as the icon of DRAW-SVG, mapping, technical, presentation slides, etc. ..

SVG at a data URI for background images.... just because you can, doesn't mean you should.

Iconic Font is a free set of 263+ finest icons in one font for your next project. @font-face: .im { display: inline-block; font: 24px/1 "iconmonstr-iconic-font"; text-rendering: auto; }

You should have a look at http://iconmonstr.com Iconmonstr.com has a growing collection of SVG icons which you can download and use for free

Another Use Case: The fill property is one of many reasons SVG is a much more flexible option than typical image files. Let's take icons, as an example. We might have the same set of icons but in two different color schemes. Typical image files (such as JPG, PNG and GIF) would require us to make two versions of each icon — one for each color scheme. SVG, on the other hand, allows us to paint the icons in using the CSS fill property: .icon { fill: black; } .icon-secondary { fill: orange; }

Fortunately, CSS3 introduces the background-size property which allows backgrounds to be stretched or squashed. It’s ideal if you’re creating a template using Responsive Web Design techniques. There are several ways to define sizing dimensions — view the CSS3 background-size demonstration page.

Let's take a look at what it takes to build a grid overlay with CSS. It will be responsive, easily customizable and make heavy use of CSS variables (known more accurately as "CSS custom properties"). If you aren't familiar with custom properties, I'd highly recommend reading What is the difference between CSS variables and preprocessor variables? and watching Lea Verou's enlighting talk on using them. This grid overlay that we're building will consider a developer tool, as in, a tool just for us, not really our users. So, let's not worry too much about browser support (If you do care, check out caniuse… data on custom properties). While it's impossible to preprocess custom properties to behave exactly the same as native support, if you use them just like you would preprocessor variables, tools like the postCSS plugin cssnext can transform them into CSS compliant with older browsers.

Let's look at some ways we can use the browsers DevTools to do design work. There are a few somewhat hidden tricks you mind find handy!

A CSS lock is a Responsive Web Design technique that lets you transition smoothly between two values, depending on the current viewport size, rather than jump straight from one value to the other.

The reason this is bad is that the CSS will hide the iframe no matter what and users with JavaScript turned off will never see that iframe. Now I'm not usually one to go to extreme lengths to cater to that crowd, but I'm all for using better solutions that do solve that issue when they are available.

To make the video fullscreen: video#bgvid { position: fixed; top: 50%; left: 50%; min-width: 100%; min-height: 100%; width: auto; height: auto; z-index: -100; -ms-transform: translateX(-50%) translateY(-50%); -moz-transform: translateX(-50%) translateY(-50%); -webkit-transform: translateX(-50%) translateY(-50%); transform: translateX(-50%) translateY(-50%); background: url(polina.jpg) no-repeat; background-size: cover; } Conclusion: “Background” video can be a very powerful feature on a site, but with great power comes great responsibility: please use such features judiciously.

The problem with z-index is that very few people understand how it really works. It’s not complicated, but it if you’ve never taken the time to read its specification, there are almost certainly crucial aspects that you’re completely unaware of.

The box-decoration-break property lets you control how box decorations are drawn across the fragments of a "broken" element. An element can break into fragments at the end of a line, over columns, or at page breaks

Centering in CSS is a pain in the ass. There seems to be a gazillion ways to do it, depending on a variety of factors. This consolidates them and gives you the code you need for each situation. Select the type of content you want to center in a parent div and the size of the parent.

Add any overflow value other than visible to your container: div#nav { overflow:auto; } Then add width to restore the width : div#nav { width: 100%; overflow:auto; }

All About Floats By Chris Coyier On July 8, 2009

For the past three years, I've done a lot of research and experiments related to the idea of style scoping and element queries in CSS. Since experimenting with element queries, I've noticed a big transformation in how I write HTML, and the fine-grained nature of element queries has improved the way I write CSS too. In this article I am going to explain why I love Element Queries and how you can get started easily.

What are Element Queries? Element queries are a new way of thinking about responsive web design where the responsive conditions apply to elements on the page instead of the width or height of the browser. Unlike CSS @media queries, @element Queries are aware of more than just the width and height of the browser, you can write responsive conditions for a number of different situations like how many characters of text or child elements an element contains. Another concept that element queries brings to CSS is the idea of ‘scoping’ your styles to one element in the same way that JavaScript functions define a new scope for the variables they contain.

listing of bookmarks folder icon user styles _ /* = NO Folders Icons BOOKMARKS - No bookmarks bar icons by xd_1771 = */ /* ==== NO Folders Icons BOOKMARKS - No bookmarks bar icons by xd_1771 - UP - TWEAK === */ toolbarbutton.bookmark-item > .toolbarbutton-icon { display: none !important; }

you can use Firefox menu->Developer->BrowserToolbox to examine UI elements and play with CSS. After you open it, click OK in the main browser window, wait a few seconds for the toolbox to initiliaze, then use the first button in its toolbar to pick an element (bookmarks button in your case).

Why is my CSS broken after implementing the namespaces I showed above? The namespaces can only be resolved within your CSS when you add @namespace declarations corresponding to your XML namespaces. This is described in the spec. Make sure your stylesheet has the following statement, placed at an appropriate location (directly after all @charsets and @imports): @namespace active 'http://www.xxx.com/tracks/active'; If you have styles for the rest of your namespaces, you'll need to include those as well: @namespace completed 'http://www.xxx.com/tracks/completed'; @namespace inactive 'http://www.xxx.com/tracks/inactive';
