我有以下形象标签:
<%= image_tag @user.photo.url(:large) %>
我怎么能把边界颜色带给安全局的这种形象的一面? html将会产生什么结果?
a. 添加一门或一门以上图像:
<%= image_tag @user.photo.url(:large), :class => "style_image" %>
之后,使用 c作体:
.style_image {
border-right: 1px solid #000;
}
by using "style" option:
<%= image_tag @user.photo.url(:large), :style => "border: 1px solid red" %>
for further info, please check the API.
你们也可以说一行风格。
<%= image_tag @user.photo.url(:large), :style => "float :left;border 1px solid #00000;" %>
......。
在更新的铁路中,有“更好的”方式:
<%= image_tag( filename_in_public_folder , alt: Description , style: display: block; margin: auto; width: 40%; )%>
这是这样做的简单方式。
<%= image_tag("example.png", :style => border-right: 1px solid #000; )%>
For others who come across this on Google. If you use an image tag in a different way, you can still add css class to it, but it s just different syntax. Sometimes you need to use an external server. (Deployment on Heroku? => Amazon s3)
<%= image_tag("https://s3-us-west-2.amazonaws.com/mybucketname/user_photo.png", class: "style_image") %>
