Getting Around Internet Explorer’s 4,096 CSS Rule Limit… Again

In 2012, I wrote about handling IE8’s limit of 4096 selectors in any single CSS file. It’s been several years since then… and this is still a problem. Using SCSS and frameworks makes it distressingly easy to hit these limits. In a perfect world, we’d be able to avoid them altogether, as the bloat is […]

Selectivizr – Pseudo Selector Support for IE

Working with visuals for HTML forms can be painful. They are ugly, clunky, and tend to be different in each browser. One way we have been spicing up our forms is by improving the look of the checkbox and radio button areas. Making toggles and visual cues for standard form elements will make forms feel […]

Getting Around Internet Explorer’s 4,096 CSS Rule Limit

Browser incompatibilities are not quite my favorite bugs to find. I recently got a bit more gray hair when I found out that Internet Explorer can’t handle more than 4,095 (2 ^ 12 – 1) selectors in a single CSS file. This is easy to run into when you’re using a framework like Rails’ asset […]

When we first started building up our web test suite using Watin, we quickly started getting this error: System.Runtime.InteropServices.COMException : The interface is unknown.System.Runtime.InteropServices.COMException : The interface is unknown. If you tell IE to use Protected Mode even for Local Intranet sites, these errors don’t happen. We weren’t the first to have this problem. The […]

File Upload Testing in IE8 with WatiN

A .NET MVC application we’re currently working on contains a feature involving image uploads. We’ve had an excellent experience so far using WatiN and SpecFlow together for system testing, but testing file uploads always adds an extra degree of complication. This was no exception, but I’m quite pleased with the outcome. The first hurdle I […]

jQuery Ajax Memory Leak in IE8

I was surprised to find out last week that Ajax calls made with jQuery 1.4.2 leak memory in Internet Explorer 8. The web application I am working on includes a page on which a user will spend much of their time. As the user navigates through various subsections of the page (we are using sammy.js […]
