Creating Alpha Channel JPEGs Using SVG

November 7th, 2015 by zoltan · 2 Comments

sun-alpha-thumb PNGs with alpha channels are great, but they can take up a lot of bandwidth. Alternative image formats such as JPEG-XR, JPEG 2000 and WEBP are more efficient, but they are not supported by FIrefox (and may never be). In comes a full cross-browser solution: SVG files that encapulate a JPEG with an alpha channel. This post will cover how to create these image files a number of different ways, and show how you can animate these images as well.

Augment Photos With CSS3 matrix3d() Transforms

July 16th, 2015 by zoltan · 1 Comment

teaser It’s possible to super-impose dynamic HTML content on top of a photos using 3D transforms to give the appearance that it is part of the picture. However, using a combination of translate3d(), scale3d() and rotate3d() functions to do this is difficult. This article discusses how to use the matrix3d() CSS transform with the Matrix Construction Set to get pixel-perfect 3D transforms easily and without any knowledge of matrix arithmetic. It also discusses the differences between matrix() and matrix3d(), as well as what fallbacks to use for browsers that don’t support transforms.

Using WEBP/JPEG 2000/JPEG-XR/APNG Now With Picturefill and Modernizr

January 14th, 2015 by zoltan · 11 Comments

teaser WEBP, JPEG 2000, JPEG-XR, APNG … these image formats have features that are not available in the traditional GIF/JPEG/PNG/SVG image stack, like animation, lossy compressions paired with alpha channels and better quality at higher compression levels. However, each browser seems to support only some of these formats. With the <picture> element, along with the picturefill polyfill, you can use these great formats today while using the older formats for an old-fashioned fallback. This blog post will explain how to use picturefill or modernizr to use these formats, why you would want to use these image formats, and what tools you can use to generate them.

Fixing Typography Inside of 2-D CSS Transforms

May 4th, 2014 by zoltan · 2 Comments

If you’ve been using CSS3 Transforms, you have probably seen that sometimes, transformed text that is not spaced correctly, is rendered with jagged edges, and letters are placed correctly on the transformed baseline. Furthermore, transformed text becomes smoother when animating, but about a second after the animation stops, you’ll see it reverts back to its former jaggedy self. This effect is really pronounced in Windows, but also appears in Mac OS X and Linux browsers. What is a typography nut to do? In this article, I present three fixes to this issue using the CSS perspective, filter and outline properties.

Better Web Typography With font-weight, Autohinting and font-feature-settings

September 20th, 2013 by zoltan · 2 Comments

After playing around with the technology for the past two years, I have done research on how to improve the look and legibility of @font-face type. Faux-bolding and faux-italicizing (i.e. “obliquing”) can be easily avoided a lot more easily with new browsers (and in some cases, even older IE!). Fonts that look horrible in Windows can be improved with autohinting. And best of all, advanced features of OpenType fonts, like ligatures, alternative glyphs, and other character variations are almost in all the major browsers (Safari, the only holdout, will have it later this year). Let’s see how we can put this all into practice today.

Cross-Browser SVG Text-Paths Without JavaScript — Even In Older IE.

May 20th, 2013 by zoltan · No Comments

c-is-for-cookie Designers have been using textpaths for years in print, but doing this on the web is a little tricky. SVG, which supports textpaths in modern browsers, is not supported by IE <= 8. Older IE does, however, support VML, another vector markup format that can do textpaths as well. After playing around, I found it is possible to put both on a web page and even code common CSS to style them — all without JavaScript. I’ll explain how we can layout and style textpaths in all browsers (including IE <= 8) as well as what a Bézier Curve is, and a bit of a code that will show how to push text on a path as well tween a textpath.

How To Create SVG Paths Easily Using The GIMP

April 26th, 2013 by zoltan · 6 Comments

When writing my blog post about Clicking Through Clipped Images Using CSS Pointer Events, SVG Paths and VML, I needed to create SVG paths. The problem is that they look so complicated and are not intuitive enough to produce by hand. However, I came across a cheap and simple way of creating SVG paths using the GIMP. People tell me I am also cheap and simple, so maybe that is why I love this solution so much (It takes only six simple steps!) So, for the rest of you like-minded people, I would like to share it this solution with you.

Clicking Through Clipped Images Using CSS Pointer Events, SVG Paths and VML

April 26th, 2013 by zoltan · 3 Comments

In HTML documents, setting a DOM object’s pointer-event property to none will result in any mouse event to pass through that node to the nodes positioned underneath. This, along with SVG Paths and some VML fallbacks for IE, can be used to make some very interesting effects. This article covers how to do this in depth, along with some interesting gotchas in even modern browsers that affect performance. You’d be surprised what eye-candy you can produce today, in both older versions of Internet Explorer to the most modern mobile device.

CSS3 Pseudo-Classes and HTML5 Forms: Their Limitations and a Possible Solution

November 5th, 2012 by zoltan · 2 Comments

I have been playing around with HTML5 Forms for a while now, and one of my favorite parts of the HTML5 Forms spec is the use of CSS3 pseudo-classes to show the validation state of the form fields to the user. I believe these validation hints make a better user experience and makes the process of filling out the form less frustrating. However, I think there are some shortcomings in the existing psuedo-classes that produce these validation hints. I hope that this article will start a discussion for a possible solution that could be easily added to the CSS3 UI specification.
