在打印预览模式下使用Chrome的Element Inspector?

余生颓废 提交于 2020-07-24 07:37:53
问题: I am working on developing a website and need to work on the print view. 我正在开发一个网站,需要处理打印视图。 Typically when I have layout issues I use Chrome's Element Inspector. 通常,当我遇到布局问题时,我会使用Chrome的Element Inspector。 However this does not exist in print preview mode. 但是,这在打印预览模式下不存在。 Is there a Chrome plugin or some other way to change your viewing medium within chrome itself, to view a page as a printer would? 是否有Chrome插件或其他方式来更改Chrome本身的查看媒体,以打印机的形式查看页面? I suppose it doesn't have a be a Chrome specific solution, but that is my primary browser so it would be nice to have an in-browser solution.

LeetCode 1150. 检查一个数是否在数组中占绝大多数(二分查找)

梦想与她 提交于 2020-07-23 21:45:59
文章目录 1. 题目 2. 解题 2.1 暴力 2.2 二分查找 1. 题目 给出一个按 非递减 顺序排列的数组 nums,和一个目标数值 target。 假如数组 nums 中绝大多数元素的数值都等于 target,则返回 True,否则请返回 False。 所谓占绝大多数,是指在长度为 N 的数组中出现必须 超过 N/2 次 。 示例 1 : 输入:nums = [ 2 , 4 , 5 , 5 , 5 , 5 , 5 , 6 , 6 ] , target = 5 输出: true 解释: 数字 5 出现了 5 次,而数组的长度为 9 。 所以, 5 在数组中占绝大多数,因为 5 次 > 9 / 2 。 示例 2 : 输入:nums = [ 10 , 100 , 101 , 101 ] , target = 101 输出: false 解释: 数字 101 出现了 2 次,而数组的长度是 4 。 所以, 101 不是 数组占绝大多数的元素,因为 2 次 = 4 / 2 。 提示: 1 <= nums . length <= 1000 1 <= nums [ i ] <= 10 ^ 9 1 <= target <= 10 ^ 9 来源:力扣(LeetCode) 链接:https://leetcode-cn.com/problems/check-if-a-number-is

1-Two Sum

1 . Two Sum Given an array of integers, return indices of the two numbers such that they add up to a specific target. You may assume that each input would have exactly one solution, and you may not use the same element twice. Example: Given nums = [2, 7, 11, 15], target = 9, Because nums[ 0 ] + nums[ 1 ] = 2 + 7 = 9, return [ 0 , 1 ]. Approach : One-pass Hash Table To improve our run time complexity, we need a more efficient way to check if the complement exists in the array. If the complement exists, we need to look up its index. What is the best way to maintain a mapping of each element in

Apply blend mode to drop-shadow only

眉间皱痕 提交于 2020-05-29 06:53:29
问题 Is it possible to blend only the drop-shadow of an element with the color of the element it is overlapping? For example: I have one element overlapping the other. The element on top has a light-grey drop shadow. The element below is black. I don't want any blend applied to either of the elements themselves but want the drop-shadow of the overlapping element to blend with color of the element below, creating a darker grey where the shadow falls on the overlapped element. If I wanted to apply

spawn & drag of SVG elements - approach

你。 提交于 2020-05-12 07:12:42
问题 I am on my learning curve for Javascript/SVG combo (animating and making interactive SVGs). I wanted to create a code snippet where menu elements ("inventory") can be dragged over to the main screen ("canvas") while the originating element would remain in its place (as if one would move a copy of it off the original element). Here I crafted the code snippet as best as I could: http://codepen.io/cmer41k/pen/f2b5eea274cdde29b0b2dc8a2424a645 So I sort of managed to do something but its buggy: I
