Put title/alt attributes into CSS :after { content: image }?

由 不问归期 提交于 2019-12-03 12:25:38
I’ve got the following CSS to add a PDF icon to any link that links to a PDF: a.pdf-link:after { padding-left: 2px; content: url(../images/icon-pdf-link.gif);} Is it possible to put some title and alt attributes on this image? I would like it so that the user is able to hover over the icon and get some text like “This links to a .pdf file.” Which I’ve typically done just by putting title attributes to it, but can’t figure out if I can do that through this method. No, content only accepts raw text and image data, not HTML. You need to use JavaScript to dynamically add tooltips to your existing

“apple-mobile-web-app-title” on Android

is there an equivalent to iOS 6 meta tag apple-mobile-web-app-title for android web-applications? Something that gives you the possibility to define a long title and a short title. <title>Long name</title> <meta name="apple-mobile-web-app-title" content="Short name"> This is possible using the "application-name" meta tag. However it only appears to work with chrome. Firefox and the android browser don't use the title tag <head> ... <meta name="application-name" content="Awesome App!"> ... </head> From, Usage in web applications section http://w3c-webmob.github.io/installable-webapps/ Chrome

I am using a viewpager "tabs + swipe" and I would like to set different titles in the actionBar for each fragment so that when I switch, title changes. I tried several things without success, only the last title displays... and does not change anymore when I switch... First, make your activity implement an OnPageChangeListener . Then, when you create your ViewPager , you can use mViewPager.setOnPageChangeListener(this) so that your activity will receive callbacks when the page changes. Finally, you need to implement the OnPageChangeListener callbacks. Your onPageSelected() method should be

gamma校正可使得图像看起来更符合人眼的特性。gamma校正公式常写为Out= In gamma 或者Out= In 1/gamma 形式，式中，In表示Input image, Out 表示Output image。本文采用第一种形式。gamma校正前后图像的亮度对比如下图所示: 1. opencv-python实现gamma校正 1 import cv2 2 import numpy as np 3 import matplotlib.pyplot as plt 4 5 gamma1 = 0.4 6 gamma2 = 2.5 7 8 imgIn = cv2.imread('messi.jpg', 0) 9 imgIn = imgIn.astype(float) / 255 10 11 out1 = imgIn ** gamma1 12 out2 = imgIn ** gamma2 13 14 out1 *= 255 15 out1[out1 < 0] = 0 16 out1[out1 > 255] = 255 17 out1 = out1.astype(np.uint8) 18 19 out2 *= 255 20 out2[out2 < 0] = 0 21 out2[out2 > 255] = 255 22 out2 = out2.astype(np.uint8) 23 24

Is it possible to add title to charts?

由 浪子不回头ぞ 提交于 2019-12-03 10:55:05
I want to add a title to a chart, like in the gauge example or a pie chart. I want to display a title under or on top of the chart. Is this possible? I've been looking and can't find anything about this. if so , any tip to share? it would be something like this EDIT : i found there is a property to create text sprites for the title or any labels at the Ex.draw package . but i couldnt understand how to use it.. anybdy here have done the same? Since Ext.chart.Chart is an Ext.draw.Component, you can add sprites as items of it. Try to use this: Ext.create('Ext.chart.Chart', { default chart

Matplotlib placement of text e.g. suptitle inside the frame

由 自古美人都是妖i 提交于 2019-12-03 10:52:18
问题 So far i have placed my suptitles above the frame, like this: How can i get the suptitles from above the frame into the frame? So far i have a solution that just prints a text and sets it on the right position with computing xlim and ylim. However this is errorprone and if the text is different it just looks aweful. Is there a way to set the suplabel into the frame? Or just place text below the frame and centered? it would be really convenient, if i did not need to know about the data that is

Trouble left-aligning UIButton title (iOS/Swift)

由 别来无恙 提交于 2019-12-03 10:26:13
I'm having a problem left-aligning a UIButton 's text. I also tried changing it to .Right but it still stays centered. I also tried aButton.imageEdgeInsets = UIEdgeInsets(top: 0, left: 20, bottom: 0, right: 0) instead of aButton.titleLabel?.textAlignment = .Left but that doesn't change anything either. Is there an alternative way to programmatically change the alignment of a UIButton title's? allButtonViews = UIView(frame: CGRectMake(0, 44, 100, 100)) allButtonViews.backgroundColor = .redColor() let campusButton = UIButton(type: UIButtonType.System) as UIButton aButton.frame = CGRectMake(0, 0,
