html5 - Where could some html tags be necessary? -

-

i walking through new html 5 features , saw , tried lot of new tags see kind of affect have on browser didn't see difference.

so lets talk <time> tag example :

if write down <time>10:00</time> shows 10:00 on page mean expecting advanced formatting. example, if write <time>10</time> format 10:00 instead of showing 10 on page.

also example can <time datetime="2008-02-14">valentines day</time> shows valentine days on page , nothing more. no tooltip, not fancy animation nothing them.

they tags this, , if needed use span or else , use kinda js code make more appealing , that's all.

so not talking <time> tag here, other tags that.

eventually, question why , need use them.

my best guess make source code more readable codes , crawlers maybe or can used semantic web. these answers didn't satisfy me.

they used adding semantic meaning markup. instance:

<div class="post"> <h1>example blog post</h1>    <div class="entry">       <p>blog text goes here...</p>    </div>    <div class="entryfooter">       <p> posted in example category.</p>    </div> </div>

is not readable using html5 tags of:

<article>    <header>       <h1>example blog post</h1>    </header>    <p>blog text goes here...</p>    <footer>       <p>posted in example category.</p>    </footer> </article>

it helps make markup more readable developers , think makes styling lot easier. <time> tag falls in boat provides more semantic meaning in markup <span> tag would. way programs in future or browsers might able use semantic data change time per user's local time zone example.
