Also, is it possible to now copy this conditional formatting to work for every cell in the column, but only affect the cell's row? Also with this the cell stays hightlighted if it is left blank, is this right? like

Using that program I get the actual code for each image that I create, thus allowing me to choose to insert code or use an actual image. I was wondering what would consume less memory, the image code or an actual PNG? I know an image memory consumption is width x height x 4 = bytes in memory but I have no idea whether an image that is generated by code is more memory efficient, less memory efficient or breaks even? This decision is particularly important given the different

Here are three ways I noticed in various code. I roughly noticed that: if I'm going to put Record into a std::set , map , priority_queue , … containers, the version 2 works (probably version 3 as well); if I'm going to save Record into a vector<Record> v and then call make_heap(v.begin(), v.end()) etc.. then only version 1 works. struct Record { char c; int num; //version 1 bool

What is the easiest (is there an easy way?) to use Less (in combination with Sass/Scss) in the rails 3.1 assets pipeline? I want to load a file like foo.css.less like i would do for bar.css.scss I found some wonky solution that does not work for me (haven't tried a lot) : https://github.com/thisduck/ruby-less-js/issues/2 The idea would be to use Twitter Bootstrap in a clean way. Thanks in advance If you only want to use bootstrap, you can do it by including the 'less-rails' and 'less-rails-bootstrap' gems in your GemFile. Then, you can @import bootstrap in your .css.less files: @import

I'm trying to make a LESS mixin that will give me this output: .resource:nth-child(8n+1) { clear: left; } I've got this so far: .wrap-every(@n) { &:nth-child(@n + "n+1") { // parse error on this line clear: left; } } .resource { .wrap-every(8); } But it's giving a parse error on the indicated line ParseError: Unrecognised input Is there a way to do this? Less >= 1.4 you could do something like this: .wrap-every(@n) { &:nth-child(@{n}n + 1) { clear: left; } } this should have the desired output. Without any hacks needed. in older versins of Less you can try simple string interpolation : .wrap
