There were two descriptions explaining what a strong tag is.
The More Information links were duplicated.
Also corrected inconsistent and incorrect markdown/html formatting.
Removed space between "/" and "body" in line 27 to correct the spacing.
Added "use" in between "container" and "several" to make grammatical sense in line 32. Also added a space between "semantic" and the parathesis in the same line to make text look cleaner.
Added "and" between "<header>" and "<footer>" because there are two items in line 33.
Note: In "Introduction of semantic tags," the grammar and sentence structure does not make sense. I tried to correct it, however, it may not be the right correction and should be reviewed.
* Corrected markdown and code sample formatting
Added code highlighting to `<p>`, to prevent it being interpreted as a new paragraph.
Also made indentation in the code sample consistent.
* Fixed typo and formatting
Before modifying this, line 23 quote, "by default the first checkbox will come automatically" even though the checked attribute is in the second input element, not the first.
Changed "ascribe" to "attribute" in line 7 so make reading easier. Also changed "The" to "This" on lines 38, 40, 42, 44, and 46 to show that the element possessed that attribute and to help make it easier to read.
At the end of the sentence, after "more clearly explain the purpose of each section of a website" add "and make the structure of the website easier to understand."
Add the following paragraph after the doctype declaration on Line 55:
"It is important to note, that while "DOCTYPE" is shown in uppercase letters here. The keyword "DOCTYPE" is case-insensitive and can be uppercase or lowercase. This simplification is part of the reason HTML5 pages are compatible with old and new browsers, and also compatible with the browsers on mobile devices."
Changed the examples, added more details about each formatting method, and cleaned up grammar. Also made the text easier to read and comprehend, as well as more attractive.
