divs in rails not aligning properly

I'd like to create a grid of these divs:

.category_result {
    width:178px;
    margin-left:10px;
    margin-right:10px;
    height:180px;
    font-size:13px;
    display:inline-block;
}

but when I insert the following lines into them, they are no longer aligned horizontally:

 <% @nonempty_category_companies[index].each do |cmp|%>
  <div class开发者_运维知识库="category_company_name">
  <%= link_to company.company_name, :controller=>"companies", :action=>"show", :company_name =>"#{cmp.company_name}" %>
  </div>
<% end %>

any idea why? thank you.

btw:

.category_company_name {
    padding-top:7px;
    padding-left:2px;
    display:inline-block;
}

======== edit: i am inserting the generated html

I don't know Ruby, so I'm not 100% sure I know what your generated HTML looks like, but I guess the issue is that you're not specifying vertical-align.

Try adding:

.category_result {
    vertical-align: top
}

And/or:

.category_company_name {
    vertical-align: top
}

See these links to understand why you need vertical-align with display: inline-block:
