there two mistakes:
1.The below images src is wrong:
“This is a paragraph with class="success" and a link.”
“This is a paragraph with class="error" and a link.”
“This is a paragraph with class="notice" and a link.”
2.The second big tag have different effect between the online demo and local file.
“I am the big tag example”
online demo's "the big tag" size is equal adjacent text.
but when download the BlueTrip framework,open the index.html,the "the big tag" size is big then adjacent text.
