html - why html5 is used necessarily? -

-

this question has answer here:

i'm surprisingly amazed @ following codes found in joomla2.5 template: beez5

<?php if(!$templateparams->get('html5', 0)): ?>         <div id="header">             <?php else: ?>         <header id="header">             <?php endif; ?>

yeah! it's age of html5 code asking if browser supports html5 add <header id="header"> tag otherwise add <div id="header">. why template not using <div id="header"> instead of both?

question: difference between old markup <div id="header"> , new markup <header id="header">? if browsers supports html5, behaves differently <div id="header"> when using <header id="header">?

php server side language, not checking @ client level, @ server.

html 5 more semantically correct, using <header> rather using <div> id header provides better seo, easier web crawlers find, , provides better accessibility (i.e. screen reader or other device can relate headers, footers, sections represent).

visual studio - TFS will not accept changes I've made to a Java project -

-
i using tfs's team explorer manage visual studio projects. recently, i've created new java project (not in visual studio) manually added tfs using source control control explorer in visual studio. after added java project tfs, made changes , bug fixes. then, went visual studio , opened source control explorer check in changes, tfs thinks no changes made. it seems needed check out project before making changes. guess erroneously expected tfs track automatically, okay. so, using source control explorer in tfs, checked out project, , tried check in pending changes. when tried check in, got following message: all of changes either unmodified files or locks. changes have been undone server. is there way convince server indeed project has changed? how can check in changes have made? thank help.
