rem 单位仅对字体大小有用吗?(Are rem units only useful for font-size?)

问题 我将 rems 用于所有类型的元素,例如: html: 62.5%; .element { font-size: 1.6rem; margin: 2rem 0 1rem 0; padding: 1rem; min-height: 3rem; height: 100%; } 我已经阅读了一些关于使用 REM 而不是 PX 的优势的文章。 我目前正在使用 REM,但我开始考虑它是否只对字体大小有用。 那么,REM 是在其他元素中有用还是在所有元素中使用它们有点过头了? 回答1 支持在整个布局中使用 rem 或 em 单位的一个重要论据是,您的整个布局将随文本缩放。 这对于旧浏览器的可访问性很重要,它提供了增加字体大小的选项,而不是大多数浏览器现在提供的“缩放”功能。 为了使网页更易于阅读,可见度低的人通常会增加字体大小——而在对页面上的所有元素使用 rem 或 em 单位的网站中,整个页面都会缩放。 这个论点现在不太相关,但对于旧版浏览器支持仍然很重要(许多学校和办公室仍在使用 IE6!)。

iPhone/iPod Touch:Info.plist:无法验证图标尺寸,未找到图标(iPhone/iPod Touch: Info.plist: Unable to verify icon dimensions, no icon found)

问题 我发布这个的原因是我已经尝试了所有在线编写的解决方案,但没有一个对我有用。 我错过了什么? 任何人都可以帮忙吗? 通过 xcode 4.6 中的档案工具验证我的应用程序时,这是我收到的错误消息: iPhone/iPod Touch:Info.plist:无法验证图标尺寸,未找到图标。 您必须定义 CFBundleIcons、CFBundleIconFiles、CFBundleIconFile,或提供一个 57x57 的默认 Icon.png。 它也给了我同样的 iPad 错误,虽然我的应用程序不是为 iPad 设计的,并且在 iOS 应用程序目标中,设备设置为 iPhone。 我不知道为什么 iPad 被列为错误。 我什至尝试上传 iPad Icon-72.png,但错误仍然存​​在。 我怎样才能摆脱这个错误? 我有 Icon.png、Icon@2x.png 和 Icon-72.png,这些图标在模拟器和设备上都能正常工作。 我的尝试: 在 Build Settings 中,我将 Compress PNG Files 设置为 NO。 没有解决! 我删除了图像,再次推送它们,清理、构建和验证。 没有解决! 我尝试了其他解决方案。 没有解决! 我尝试将“图标已经包含光泽”设置为否。 没有解决。 这是我的窃听错误的图像: 回答1 完全相同的问题发生在我身上。

iPhone/iPod Touch: Info.plist: Unable to verify icon dimensions, no icon found

The reason I'm posting this is that I have tried all solutions written online and none has worked for me. What is it that I am missing? Anyone can help? While validating my app via the Archives tool in xcode 4.6 This is the error messages I am getting: iPhone/iPod Touch: Info.plist: Unable to verify icon dimensions, no icon found. You must define CFBundleIcons, CFBundleIconFiles, CFBundleIconFile, or provide a default Icon.png that is 57x57. It is also giving me the same error for iPad, though my app is NOT designed for iPad to start with and in the iOS Application Target, Devices is set to

Creating table with different row dimensions

Let's say I got a table like this: data <- c(1,2,3,6,5,6,9,"LC","LC","HC","HC","LC","HC","ALL") attr(data,"dim") <- c(7,2) data [,1] [,2] [1,] "1" "LC" [2,] "2" "LC" [3,] "3" "HC" [4,] "6" "HC" [5,] "5" "LC" [6,] "6" "HC" [7,] "9" "ALL" Now I want to manipulate the data so it looks like this: [,"LC"] [,"HC"] [,"ALL"] [1,] "1" "3" "9" [2,] "2" "6" [3,] "5" "6" Is there a way to do this in R or is it just impossible and should I try another way of getting access to my data?

Display woocommerce product dimensions in separate lines

I found the way to display the dimensions in separate lines by copy product-attributes.php file to my child-theme and replace: <?php if ( $display_dimensions && $product->has_dimensions() ) : ?> <tr> <th><?php _e( 'Dimensions', 'woocommerce' ) ?></th> <td class="product_dimensions"><?php echo esc_html( wc_format_dimensions( $product->get_dimensions( false ) ) ); ?></td> </tr> <?php endif; ?> with: <?php if ( $display_dimensions && $product->has_dimensions() ) : ?> <tr> <th>Length</th> <td class="product_dimensions"><?php echo $product->get_length() . get_option( 'woocommerce_dimension_unit' )

Handling a Many-to-Many Dimension when all dimensional values have 100% importance

I'll at least try to keep this succinct. Let's suppose we're tracking the balances of accounts over time. So our fact table will have columns such as... Account Balance Fact Table (FK)AccountID (FK)DateID ... Balance ... Obviously you have an Account Dimension Table and a Date Dimension Table. So now we can easily filter on Accounts or Dates (or date ranges, etc.). But here's the kicker... Accounts can belong to Groups -- any number of Groups at a given Date. Groups are simply logical abstractions, and they have no tangible meaning aside from reporting purposes. An Account being in 0, 1, or 17

Are rem units only useful for font-size?

I'm using rems for all kind of elements such as: html: 62.5%; .element { font-size: 1.6rem; margin: 2rem 0 1rem 0; padding: 1rem; min-height: 3rem; height: 100%; } I've read some articles regarding the advantages of using REM and not PX. I'm currently using REM overall but I've began to think about if its only useful for font-size or not. So, is REM useful in another elements or using them in all the elements is a bit overdone?

find the dimensions of a dynamically loaded but DOM-appended image using jquery?

I'm loading the source of an image dynamically using ajax, where s is this source. I create an image element in the DOM, assign it this source once it's loaded, and then append it to a div called imgwrapper. Then I try to get the image's dimensions, but it doesn't work. I'm aware you can't get the dimensions of an image that's dynamically loaded, but not even after being appended to the DOM? My code is as below: //use ajax to get value of s (the image source) img = document.createElement("img"); img.src = s; $('#imgwrapper').appendChild(img); console.log($('#imgwrapper').find('img').width())
