问题描述
我是电子邮件设计的新手。我连续有一张图片，一些文字和一个按钮。在移动设备上查看时，图像必须是静态的，并且按钮必须位于文本下方。因此，图片和文字+按钮必须并排放置。我用过div和嵌套的div。它可以在移动设备上正常工作。但是，在某些基于Web的邮件客户端（例如AOL，Yahoo和Gmail）上，布局已中断。在comcast和Outlook Web上正常工作。不知道我在做什么错。请帮忙。
在comcast网络上正确呈现。
在基于Yahoo Web的邮件上呈现不正确。
这是我使用的代码：
error[E0597]: `callback` does not live long enough
> | impl<'a> Data<'a> {
> | -- lifetime `'a` defined here
> | fn mut_func<F: FnMut(u32) -> () + 'a>(&mut self,mut callback: F) {
> | self.o.push(&mut callback as &mut dyn FnMut(u32) -> ());
> | ------------^^^^^^^^^^^^^------------------------------
> | | |
> | | borrowed value does not live long enough
> | argument requires that `callback` is borrowed for `'a`
> | }
> | - `callback` dropped here while still borrowed
use std::any::Any;
use std::mem;
use std::rc::Rc;
use std::cell::RefCell;
struct Event<'a> {
obs: Vec<&'a mut dyn FnMut(u32) -> ()>,}
impl<'a> Event<'a> {
fn subscriber<F: FnMut(u32) -> () + 'a>(&mut self,mut callback: F) {
self.o.push(&mut callback as &mut dyn FnMut(u32) -> ());
}
}
fn main () {
let mut e = Event {obs: Vec::new()};
let x = 3;
e.subscriber(|n| {x+n;});
}
解决方法
我在玩您的代码，看来您在以下一行上缺少width:100%;：
<div style="display:inline-block; margin: 0 -1px; max-width: 400px; min-width:160px; vertical-align:top; padding-top: 40px;" class="stack-column-2half mobile-padding1">
添加后，联系人链接将返回与 John Smith 和标题标题相同的行。
您可以尝试下面的代码，看看它是否适合您。我必须在表格行周围添加表格代码，以使渲染正常工作。
<table width="100%" border="0" cellspacing="0" cellpadding="0">
