Bootstrap ) into my site-- the problem is I'd like to apply the Bootstrap styles only to a specific region of the page. When I include Bootstrap, it applies its styles to the entire page, restyling all tables, divs, etc. Is it possible to only apply Bootstrap to a region (say a parent div or something?)

To solve this problem, I thought I would subset first all columns with names starting with __ ,

Is it possible to do that without handling each paragraph element, but just attach somehow style to div element and all inside paragraphs would be affected? Maybe with jquery. It sounds for me like dynamical change of the stylesheet, is it possbile? The right recommendation in answer's comments. Thanks. 回答1: Without using classes: /* using CSS */ div p { color: #ff0000; } // using jQuery $("div p"

C : stack memory, goto and “jump into scope of identifier with variably modified type”,

匿名 (未验证) 提交于 2019-12-03 02:14:01
可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: I found that this refuses to compile : int test_alloc_stack(int size){ if(0) goto error; // same issue whatever conditional is used int apply[size]; give_values(apply,size); return 1; error: return 0; } The error I get is : "jump into scope of identifier with variably modified type". Eliminating the line with "goto" and the jump to error solves the issues. If I use dynamic allocation for apply, then the problem also disappear. This compiles fine: int test_alloc_heap(int size){ if(0) goto error; int * apply = calloc(sizeof(int),size); give
