Fastest way to preload/load large images

由 老子叫甜甜 提交于 2021-02-16 08:59:28
问题 Preload may not be the correct term... I have a page which loads a very large image. I wanted to wait for the large image to completly load before displaying on the page for the user. At the moment, I have a loading gif and i'm using javascript to wait for the image to load and then replace the loading gif src with the image: <img src="loading.gif" id="image" /> <script> img = 'very_large_image.jpg'; var newimg = new Image(); newimg.src = img; newimg.onload = function(){ $('#image').attr('src

Global CSS Variables vs Local Variables in terms of efficiency

由 99封情书 提交于 2021-02-16 08:55:58
问题 Does global variables in CSS are less efficient in terms of memory or in terms of efficiency as local CSS variables? so basically my question is whether there's any benefit of having variable which is declared in the the global scope and can be accessed anywhere in the CSS opposed to variables which are declared within the code block of a particular selector and scoped locally in respect to the selector. when talking about global scope i mean: :root { --mainColor: red } and local scope means:

Jquery hover - keep popup open

由 爷，独闯天下 提交于 2021-02-16 08:53:57
问题 Well, I am trying to make a button which, when a user hovers on it, will display a container which has text in it. And I am wondering if it is possible to have the container which pops up stays open if you hover down to it. It is similar to this question: However the answer on that thread does not help me, as it does not solve the issue. My code: HTML: <a href="#contact"> <div class="button"> <div class="button-text contactme"> Contact me </div> </div> </a> <div class="emailcontainer">

How can I create a style element and append to head in React?

由 ぐ巨炮叔叔 提交于 2021-02-16 06:11:31
问题 I'm currently learning React, and (more importantly) attempting to learn how react actually works. I have some generated css which I would like to append to head as a style element. In js land, this would be: const $style = document.createElement("style"); document.head.appendChild($style); const randBlue = ~~(Math.random() * 250); $style.innerHtml = `body { color: rgb(10, 10, ${randBlue}); }`; Unfortunately, in React land, things appear to be a little less straightforward in this regard.

<pre> tag loses line breaks when setting innerHTML in IE

由 拥有回忆 提交于 2021-02-16 06:01:15
问题 I'm using Prototype's PeriodicalUpdater to update a div with the results of an ajax call. As I understand it, the div is updated by setting its innerHTML. The div is wrapped in a <pre> tag. In Firefox, the <pre> formatting works as expected, but in IE, the text all ends up on one line. Here's some sample code found here which illustrates the problem. In Firefox, abc is on different line than def ; in IE it's on the same line. <html> <head> <title>IE preformatted text sucks</title> </head>
