css - Why is there more gap under logo on contact page? -

Image
if see 2 images above, see 1 has more gap under logo. both pages have same styles don't understand why there more gap on 1 of them. the page correct gap under logo @ http://snapnsolve.com/index.html , page more gap http://snapnsolve.com/contactus.html can point out problem? highly appreciated. it because id #topsochd has height of 60px in index page, has height of 40px in contactus.html. change 60px in contactus.html also. hence in contactus.html: #topsochd { height: 60px;/*not 40px*/ background-color: #ffffff; color: #fff; width: 100%; z-index: 99999; } adding float property in top-left -logo interfering problem. remove float property , instead put position:absolute automatically float logo left. #top-left-logo { position: absolute; }

jquery - Why does Bootstrap Tooltip not work correctly when placed inside a table? -

-
i trying place tooltip on table elements ( td ). although, when tooltip displayed, changes width of td element, though tooltip has position of absolute . why this? demo tooltip inserts div after specified dom element. in case, div inserted between tds, messes render flow (block vs table display). effectively, browser trying render zero-width div td border styling. update code specify valid parent element. commonly body element used. invoke $(selector).tooltip({container:'body'}); updated fiddle: http://jsfiddle.net/8s2sr/1/ if you're having hard time viewing hover state in browser inspector, right click element , preserves state inspection.
