java - Turning off IE 8 compatiblity mode -


my company uses ie8 default browser , default compatibility mode set intranet sites.

i have checked application on ie8 , , feel totally hap hazard. on chrome , mozilla , feel fine.

some 1 suggested me turn off compatible mode.

there 2 ways : 1) ie>tools>compatible view settings > ( unchecked ) display intranet sites...

2) put <meta http-equiv="x-ua-compatible" content="ie=edge" /> on jsp pages.

i checked , application looks fine when turn off compatibility mode.

my questions :

1) use of compatibility mode.

2) if turn off through jsp page, other impact. ( on ie11 , if change compatible ie9 application not work expected.)

3) turning off compatible mode solution or there else can do

4) there other impact.

from linked msdn page:

internet explorer 8 supports many compatibility modes enable different supported features , affect manner in content rendered. example,

ie5 mode renders content if displayed windows internet explorer 7 quirks mode, similar how microsoft internet explorer 5 displayed content.

ie7 mode renders content if displayed internet explorer 7 standards mode, whether or not page contains directive.

emulateie7 mode tells windows internet explorer use directive determine how render content. standards mode directives displayed in internet explorer 7 standards mode, , quirks mode directives displayed in ie5 mode. unlike ie7 mode, emulateie7 mode respects directive. many web sites, preferred compatibility mode.

emulateie8 mode similar emulateie7 mode; internet explorer uses directive determine how render content; however, standards mode directives displayed in internet explorer 8 standards mode. quirks mode directives displayed in ie5 mode.

ie8 mode provides highest support available industry standards, including w3c cascading style sheets level 2.1 specification , w3c selectors api, limited support w3c cascading style sheets level 3 specification (working draft).

edge mode tells windows internet explorer display content in highest mode available, breaks “lock-in” paradigm. internet explorer 8, equivalent ie8 mode. if (hypothetical) future release of internet explorer supported higher compatibility mode, pages set edge mode appear in highest mode supported version; however, same pages still appear in ie8 mode when viewed internet explorer 8. recommended web developers restrict use of edge mode test pages , other non-production uses because of possible unexpected results of rendering page content in future versions of windows internet explorer.

by default, internet explorer 8 uses emulateie8 mode display pages loaded internet zone. web pages loaded intranet zone or web browser control displayed in emulateie7 mode.
