Mapbox GL JS Bearing

↘锁芯ラ 提交于 2020-12-06 06:43:45
问题 Is it possible in Mapbox GL JS to get the users bearing? I would like to show the direction in which the user is facing, to assist them in navigating to nearby POI. I understand that it is possible to set the bearing of the map and also get the current bearing of it, but i need the actual real life bearing of the user. Kind of the same thing as on Google Maps: The service is intended to run as an Ionic app on iOS and Android, and the assistance in bearing is a key feature in helping them

css: dir=“rtl” VS style=“direction:rtl”

六眼飞鱼酱① 提交于 2020-08-24 06:06:28
问题 I know how to style when the direction is inline <div dir="rtl">foo</div> div[dir="rtl"] { ....; } But how to style <div style="direction:rtl">foo</div> ? Both behaves as expected (right "alignment" of text) but I need finer tweaking for some elements inside (float, text-align...) and I can't set up my rule correctly in the second case. I can't edit the html. I MUST use style="direction:rtl". 回答1: As you can't modify the HTML, a really really hacky selector would be: div[style*="direction:rtl

CSS的文本属性

喜夏-厌秋 提交于 2020-04-06 13:33:58
CSS 文本属性可定义文本的外观。 通过文本属性,可以改变文本的颜色、字符间距,对齐文本,装饰文本,对文本进行缩进等。 ㈠缩进文本 text-indent 通过使用 text-indent 属性,所有元素的第一行都可以缩进一个给定的长度,甚至该长度可以是负值。 ⑴使用负值 比如“悬挂缩进”,即第一行悬挂在元素中余下部分的左边,如下所示: p {text-indent: -6em;} 不过在为 text-indent 设置负值时要当心,如果对一个段落设置了负值,那么首行的某些文本可能会超出浏览器窗口的左边界。 为了避免出现这种显示问题,建议针对负缩进再设置一个外边距或一些内边距,如下所示: p {text-indent: -6em; padding-left: 6em;} ⑵使用百分比值 百分数要相对于缩进元素父元素的宽度。换句话说,如果将缩进值设置为 20%,所影响元素的第一行会缩进其父元素宽度的 20%。 在下例中,缩进值是父元素的 20%,即 100 个像素: div {width: 500px;} p {text-indent: 20%;} <div> <p>this is a paragragh</p> </div>⑶利用text-indent属性演示如何缩进文本首行。 ㈡水平对齐 text-align text-align 属性规定元素中的文本的水平对齐方式。

一种无限循环轮播图的实现原理

本文来自 http://www.jianshu.com/p/ef03ec7f23b2 轮播实现步骤 接下来,笔者将从各方面逐一分析 层级结构 最底层是一个UIView,上面有一个UIScrollView以及UIPageControl,scrollView上有两个UIImageView,imageView宽高 = scrollview宽高 = view宽高 轮播原理 假设轮播控件的宽度为x高度为y,我们设置scrollview的contentSize.width为3x,并让scrollview的水平偏移量为x,既显示最中间内容 scrollView.contentSize = CGSizeMake(3x, y); scrollView.contentOffset = CGPointMake(x, 0); 将imageView添加到scrollview内容视图的中间位置 接下来使用代理方法scrollViewDidScroll来监听scrollview的滚动,定义一个枚举变量来记录滚动的方向 typedef enum{ DirecNone, DirecLeft, DirecRight } Direction; @property (nonatomic, assign) Direction direction; - (void)scrollViewDidScroll:
