background image and elements on it

由 百般思念 提交于 2019-12-25 08:15:54
问题 I need to put some elements on picture: What is better approach ? use img tag and align all elements on page with relative/absolute positioning ? or use background-image css property ? I've started with img tags but now I've decided for background-image. Sadly I'm suffering with basic problems, as when I'm using background property, image is only visible when there is something on it. I believe that is very simple problem, still. Thank you for helping me out :) SCSS header { margin-top: 78px;

Sprite position not working in Objective-C, Xcode

问题 It has been a year or so since I've used Objective-C and I must have forgot something because this is stumping me. I didn't use a for loop because I wanted a delay, but I logged all these variables, r is a float, j is an integer. r and j were initialized to 0. -(void)fire{ r = j; if (j < 80) { j = j + 1; bullet.position = CGPointMake(2*r, 15); NSLog(@"r is %f", r); NSLog(@"j is %i", j); NSLog(@"position is %f, %f",bullet.position.x, bullet.position.y); NSLog(@"x is, %f", r/8); [self

问题 I'm trying to do a standard sticky footer but with unknown height. How to avoid page's contents from going behind it?

CSS Div re-sizing according to web browser

由 爱⌒轻易说出口 提交于 2019-12-25 06:52:03
问题 I have a few divs on my code all of them positioned correctly how i want it. The only problem is that they do not re size when i shrink the page. I want to be able to re size them according to the web browsers size. I do not know exactly how to do it and im worried it might mess up their correct top & left position. All of my divs are currently set as absolute positioning. 回答1: Set their sizes to percent values rather than pixels (I asume that's what you're using) 回答2: Set all divs with

官方文档位置：https://www.elastic.co/guide/en/elasticsearch/reference/7.5/analysis.html 分词 分词是指将文本转化成一系列的单词（term or token）的过程，也可以叫文本分析 es里称之为Analysis 分词器 分词器是es中专门处理分词的组件,英文为Analyzer ,它的组成如下: Character Filters 针对原始文本进行处理,比如去除html特殊标记符 Tokenizer 将原始文本按照一定规则切分为单词 Token Filters 针对 tokenizer处理的单词就行再加工,比如转小写、删除或新增等处理 分词器-调用顺序 Analyze API es提供了一个测试分词的api接口,方便验证分词效果, endpoint是_ analyze 可以直接指定analyzer进行测试 可以直接指定索弓|中的字段进行测试 可以自定义分词器进行测试 直接指定Analyzer进行测试，接口如下： POST _analyze { "analyzer":"standard", //分词器,standard是es默认分词器，如果字段里没有指定分词器，会默认使用standard "text":"hello world!" //测试文本 } 输出： { "tokens": [ { "token":

Cocos2D: Get layer's position in scene from another class

由 人走茶凉 提交于 2019-12-25 05:22:30
问题 I'm trying to retrieve the current position of the layer added as a child in a scene while a scene transition is occurring. The transition is an edited Cocos2D transition that slides the layer off the screen while a new one appears. I created my own implementation inside CCActionEase with an update method: #import "JoinedMapsScene.h" #import "JoinedMapsLayer.h" @implementation CCEaseInWithPercentMult -(void) update: (ccTime) t { [other update: powf(t,rate)]; CCScene * scene = [[CCDirector

Trying to get just “x” coordinate from pos() method python

由 泄露秘密 提交于 2019-12-25 04:42:48
问题 I'm currently having an issue getting just the x position of the cursor so I can place a marker on that x and y location. I'm using QGraphicsScene and view to create this circle object at the location of the mouse when the mouse is clicked. Since the QGraphicsEllipseItem takes 4 arguments it seems I need the x and y coordinate separate not just what the position method gives you since it gives both x and y. How do I split the two coordinates up? Here's the code: import sys from PyQt4 import
