Writing markup...
If a tag is empty and requires no closing tag, slash or no slash is okay.
<br>
<br/>
Attribute values must be provided, with the value enclosed in quotes.
alt
alt=Ham
alt=′Ham′
alt=″Ham″
Boolean (on/off) attributes can omit the redundant value (but they don’t have to).
selected
selected=selected
selected=′selected′
selected=″selected″
Deprecated vs Obsolete
These are obsolete in HTML5.
center

Continue using em when the text hasextra emphasis.
<a href=""> <h1>Post Title</h1> <p>Short description.</h1></a>
