I want the left sidebar to stick to the left side of the screen and be a minimum width in pixels, the right sidebar to stick to the right side of the screen and be a minimum width in pixels, and the

问题 i have this code: HTML <div class="bar-value"></div> CSS .bar-value{ width: 50%; height: 28px; background: #8BBDE8; } JQUERY $(document).ready(function(){ var percent = $('.bar-value').css('width'); }); the problem is that this returns the width of the div in pixels (in this case: 200px). I want that to return the value of the div in percentage (50%). Thanks in advance! 回答1: To get a percentage, you need the width of it's parent. Try this : $(document).ready(function(){ var element = $('.bar

问题 I'm working on my website and was originally using two separate images at the size of 210 by 210px for an image link (which changes into another image when hovered over.) However I found that there was always a little flicker when first hovering over the image which obviously bothered me so I decided to switch to a CSS sprite with two the images on it instead. That way I wouldn't get the flicker. Unfortunately, I can't seem to get the CSS sprite to work successfully. I'm creating my website

问题 The goal is to adjust the caret tooltip to be positioned above my horizontal stacked bar graph. oddly it works by setting yAlign to bottom and not to top. However it does not place the tooltip in the middle of the bar and it throws a TS ERROR saying Object literal may only specify known properties, and 'yAlign' does not exist in type 'ChartTooltipOptions'.
