Emmet HTML div tag with multiple words class name

Question

I did not find the answer on documentation for this question.

As we know, div.container gives

<div class="container">

However, what abbreviation shall be used for

<div class="row placeholders">

Anyone knows? Thanks.

Answer 1

From the Emmet Cheat Sheet:

p.class1.class2.class3
    <p class="class1 class2 class3"></p>

So, div.row.placeholders will give you:

<div class="row placeholders"></div>

Answer 2

To obtain this using Emmet use:

input[placeholder="Username" maxlength="254" name="username" type="text" required autofocus=""]#id_username.form-control

but required will be like required=""

But I think that's not really an "abbreviation" anymore
