I have reverted my repository to the revision before right my patch (r168684) and it does not work either. This expression can not be parsed properly because of the superfluous '(' character, but seems like it is an older issue. () However, I am glad to investigate it. The following example shows two rectangle of the same size: <div width="300px"> <div style="height:100px; width: calc((100% - 20px) / 3); border: 1px solid;" ></div> <div style="height:100px; width: calc(100%/3 - 20px/3); border: 1px solid;"></div> </div>

(In reply to comment #0) > This expression no longer works.. > > width: calc((100% - 20px) / 3; I think there has been some misunderstanding here. Your first example is a malformed expression, because a closing brace is missing from the end, and therefore it can not be parsed properly. I thought that my patch has ruined some error recovery feature, which seemed a little unlikely, since my patch did not change the CSS grammar. So I double-checked it and the expression you mentioned has never worked before. (Maybe I should report it, if it needs auto-correction at all.) But now I get it. "width: calc((100% - 20px) / 3)" is now a well-formed expression and it really does not work since my patch has landed. Thank you for your patience, I will upload a fix very soon.
