为image_tag添加标题Ruby on Rails

Question

I was wondering how to add a caption to my image_tag in rails. Here is what it loos like:

<%= image_tag "img1.jpg", :class => "rounded float-left", :height => '400px' %>

Is there anyway to add a caption beneath this picture that I have. Thanks :)

Answer 1

There's no Rails helper for this that I'm aware of, but something like this should give you a caption below the image:

<figure>
    <%= image_tag "img1.jpg", :class => "rounded float-left", :height => '400px' %>
    <figcaption>Caption goes here</figcaption>
</figure>

Answer 2

You can add a title with :title => "title" if you consider that a caption. If not, it's best to create a helper that outputs the image with a text centered and aligned immediately below.

Example:

<div class="figure">
  <img src=""/>
  <p class="caption">
    <span class="caption-text">Some caption of any length</span>
   </p>
</div>
