width

问题 In the past, I saw the next css and I was thinking if there is some actual difference between min-width: 90px; max-width: 90px; and width: 90px; 回答1: using width will simply specify fixed width over the element without paying attention to its content (so you can have overflow) : div { width: 80px; border:2px solid red; } <div> <img src="https://lorempixel.com/200/100/" /> </div> Using max-width means that the element will have an upper bound for its width. So its width can be from 0 to max

问题 I have a very simple code, which annoyingly was working and for the life of me I can not see why it is now failing: function imageSize(img){ var theImage = new Image(); theImage.src = img.attr('src'); var imgwidth = theImage.width; var imgheight = theImage.height; alert(imgwidth+'-'+imgheight); } The "img" variable being passed is the img object, obtained from: jQuery('img') .each(function(){ var imgsrc = jQuery(this); imageSize(imgsrc); }); 回答1: The image may not have loaded yet.

These divs would expand to fit the full width of a given space that has individual 1% stripes that fill that space fully. This seems to work fine in Firefox, but in Safari (and Chrome) the calculation seems to be too

问题 I wonder if it is posible to set a custom width and height on fancybox images? As a standard, the width and height of the fancybox changes in relative to the width and height of the images, but i want to be 800 width and 600 height, at all images. I want to create something familiar to the image-box on facebook, where you see the image at the left, and description and comments at the right. Could be great if someone could help me with this... :) TheYaXxE 回答1: A simpler way is to change the
