Hi
I attached the typography button HTML code below , You can copy the code and paste it in the article editor source code and check the output on front end
<div class="row example-row example-type">
<div class="col-md-8">
<!-- Button --->
<div class="example-button clearfix"><a class="btn btn-default" href="#">Normal Button</a> <a class="btn btn-primary" href="#">Primary Button</a> <a class="btn btn-success" href="#">Success Button</a></div>
<div class="example-button clearfix"><a class="btn btn-warning" href="#">Warning Button</a> <a class="btn btn-danger" href="#">Danger Button</a> <a class="btn btn-info" href="#">Info Button</a></div>
<!-- //Button --->
</div>
</div>
To make them full width add an additional button class and define the class in custom.css file .
Example :
<a class="btn btn-default fullwidth" href="#">Normal Button</a>
fullwidth is custom class > Add this class in custom.css file with 100% width style code .
code for custom.css file
.fullwidth {width:100%!important;}
