gouerdane Hi,
You shouldn't modify the bootstrap3/css/template.less file but create a conf/userstyle.css (you can use less there too).
There is no <dw_youarehere>
html tag, so your css should be .dw_youarehere
, not dw__youarehere
;-)
I usually add more CSS selectors so I'm sure the browser applies my style
body div.dokuwiki .dw__youarehere {
margin: 5px 0;
}
Could also be a cache problem. clear DW cache, clear your browser cache.
