问题 I'm working on a case resolution system, and am currently using a jquery colorbox to display a list of open tasks to the user. Users want to be able to print this list, and I guess you can do it from within the page itself by adding a JavaScript link that triggers window.print from within the iframe. However, I've also got to account for users possibly selecting print from the browser's menu. In that case, if the colorbox is open, I just want to print its contents and not the overlying page.

Bootstrap 4 CSS causing Chrome's print “Layout” to disappear

由 时光总嘲笑我的痴心妄想 提交于 2019-12-23 07:04:26
问题 I want my website users to be able to print pages in either portrait or landscape mode. When printing from Google Chrome using Bootstrap 3.3.7, the Chrome print settings has a Layout option. Simply changing the css/js to 4.0.0, the Chrome print settings no longer has the Layout option.
