CSS: @media print without external css file?

由 不打扰是莪最后的温柔 提交于 2019-12-25 00:58:07
问题 I want to print a html page in a specific way under css. But all the @media print examples seem to have an external .css file I want to be able to do it without an external file which means there will be no link rel tag: <LINK REL="stylesheet" MEDIA="print... How do I do this? 回答1: I would suggest using an external stylesheet but you can how ever do this on the same page as your HTML if you really want to, an example of this would be like so, HTML / CSS <!DOCTYPE html> <html> <head> <style>

由 女生的网名这么多〃 提交于 2019-12-24 20:22:53
问题 I’m migrating a website from WordPress to Django/Wagtail. I have all the old WP content in my media directory & it’s all being served appropriately. It would be convenient to map other URLs (specifically /wp-content/ ) to MEDIA_ROOT , for the sake of old media URLs that were hardcoded in the content. So for example a migrated asset now available at //example.com/media/uploads/2017/12/IMG_2120.jpg can also be served from //example.com/wp-content/uploads/2017/12/IMG_2120.jpg I’m sure there’s

Why does the browser load audio files several times even after preload?

由 淺唱寂寞╮ 提交于 2019-12-24 18:52:50
问题 i am monitoring the network on Safari mobile for a Web App we are developing and see this: the files get preloaded before (I guess this is why it says "(disk)" in the first of the 3 lines), and this is the network output in safari's web inspector in the network tab. Now I am wondering, why the browser seems to load it first from disk then two times(?) from the url again. Am I reading the output wrong? preloading happens like this (on user interaction): function preloadAudio(url) { console.log

Running mpg123 with FIFO control?

由 百般思念 提交于 2019-12-24 06:35:08
问题 I need to run mpg123 with a single file, such that it will autostart and autoclose, like it normally does, however, I need to be able to override this default behavior with commands sent to a fifo file. I had been running mpg123 filename.mp3 from a script, and simply waiting for it to finish before moving on. However, I'd like another script to be able to pause playback, control volume, or kill the process early, depending on the user's input. mpg123 -R --fifo /srv/http/newsctl filename.mp3

Default header p:media with pdf player

由 雨燕双飞 提交于 2019-12-24 01:24:16
问题 I'm programming a <p:lightBox> with a streamed <p:media> to preview external PDFs. It works fine but i'm getting a little handicap. When the pdf dialog is rendered it shows (on mouse over) one Header where it always display the same title: "dynamiccontent.properties". Is there an attribute or something that I can override to customize it?
