* Team, I have been using Smartline Lite theme for several years. However, recent
update looks something wrong. When I do w3 HTML validator, I am getting several
errors e.g.
* 1) in CSS line no.7, column 17362 it says “Too many values or values are not
recognized”. The value is “font-size:16px/1;line-height:1”
* 2) Error: CSS: top: Unknown dimension.
From line 15, column 44531; to line 15,
column 44533
* p:1px;top:0\9}.sd-s
* Can you pls check and correct the them urgently.
* The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fseveral-errors-on-w3-html-validator%2F%3Foutput_format%3Dmd&locale=en_US)

* Hi there,
* Thanks for using Smartline.
* Please note that we do not optimize our themes for the w3 HTML validator anymore.
* The issues could be from Smartline, but also from any plugin you are using.
* Best,
Thomas
