Sass and import directives may not be used within control directives or mixins

15 June 2015 | Category: CSS | Comments (0) in article Sass and import directives may not be used within control directives or mixins

Currently I am using both Grunt tasks grunt-sass and grunt-contrib-sass to compile sass (strictly scss). The first one is faster than second one, but second one generating source maps that just works. Unfortunately grunt-sass source maps somehow doesn’t work properly and browsers can’t use them.

I got an error message today and I’d like to share simple solution to that. The scss code more or less looks like:

@include example() {

@import 'part1';
@import 'part2';
[...]
}

Above code is compiled fine using grunt-sass, but grunt[......]

Remove CSS outlines, but keep it for keyboard navigation

14 June 2015 | Category: Accessibility | Comments (0) in article Remove CSS outlines, but keep it for keyboard navigation

I often see outline: 0; or outline: none; in CSS just because we don’t like the ring around actionable elements. Because it’s ugly sometimes and we don’t want to have it in our application / web site. I think this is mostly misunderstanding the mission of that ring. By removing this ring we solving one problem, but in the same time we creating another. I think the trade-off would be removing focus ring for the mouse users only, but not for keyboard navigation.

Let me provide here important cite from W3C about focus ring: Do not use any other[……]

Using Fiddler to force a web service to support CORS for debugging

5 June 2015 | Category: General, Tools | Comments (0) in article Using Fiddler to force a web service to support CORS for debugging

There is already nice article about Using Fiddler to force a web service to support CORS for debugging. However, it was written in 2013 and I am going here to little bit update the code for Fiddler v4.5.1.0.

So, you need to add:

public static RulesOption("Force CORS")
BindPref("fiddlerscript.rules.m_ForceCORS")
var m_ForceCORS: boolean = false;

just at the beginning of class Handlers.

In function static function OnBeforeResponse(oSession: Session) { add:

if (m_ForceCORS && (oSession.oRequest.headers.HTTPMethod == "OPTIONS" || o[......]

Right to left implementation tricks

19 May 2015 | Category: Browsers, General | Comments (0) in article Right to left implementation tricks

Introduction

At some point you may want to have bidirectional (RTL) support in your application / web site. That means you want to have a support for Arabic, Hebrew and other right-to-left languages. Before everything let me quote from W3C some of the definitions:

  • Bidirectional text – in languages that use right-to-left scripts any embedded text from a left-to-right script and all numbers progress visually left-to-right within the right-to-left visual flow of the text. (Of course, English text on this page could also contain bidirectio[……]
