问题 I can't figure out why but 2 extra pixels are added to the height of a span element. Here is an example: <!DOCTYPE html> <html> <head> </head> <body> <span style="font-size:20px;line-height: 20px"> test </span> </body> </html> In chrome debugger tools the span has a height of 22 pixels.

How to hide the toolbar in Chrome for Android tablets for a 100% high website

由 巧了我就是萌 提交于 2021-02-19 01:29:33
问题 I am trying to make a web application that is 100% of the screen width and 100% of the screen height, with a 16:9 aspect ratio. It would be awesome if I would be able to view this website fullscreen on my tablet, but unfortunately the on-screen toolbar takes up a large amount of space, making my website display neither in full height nor in full width: Now I know that since recently, it is possible to hide the scrollbar by scrolling the page down (source). However, since my web application is

Disable @media print in bootstrap?

由 时光毁灭记忆、已成空白 提交于 2021-02-18 22:20:35
问题 Is it possible to entirely disable any preconfigured @media print css styles from bootstrap without having to recompile it? The print styles applied by default could be seen here: https://github.com/twbs/bootstrap/blob/master/dist/css/bootstrap.css#L6837 I want my webpage to be printed just as seen, with all css tags applied. Especially colors, like: b { color: #ff0000; } In order to disable the print styles from bootstrap, I'd have to explicit override every property again with my custom

What does it mean to give a div a style='height:100%'?

由 こ雲淡風輕ζ 提交于 2021-02-18 22:20:06
问题 There's lots of questions on SO related to this, but the ones I scanned are all for detailed specific situations. What I want to know is, at a conceptual level, what does it mean to say: <div style='height:100%'> How high is 100%? 100% of what? [EDIT] Followup question: If 100% represents the height of the parent, but the parent is <body> and has no height other than the height of the div, then what does it mean? It seems recursively defined. 回答1: 100% of the parent container's height. See

CSS: Hidden elements still take up space on printed output

由 倾然丶 夕夏残阳落幕 提交于 2021-02-18 20:49:40
问题 I'm using css to only print a section of a page: body { visibility:hidden; } .print { visibility:visible; background-color: white; margin: 0; } The section above the element I want to print gets properly hidden in the print output, however it still takes up the area of space. I tested this by making a long vertical list of words. In the print output the same area of white space occurs without the words and then the element output occurs. This problem occurs on chrome and mozilla only. I've
