ok i got it, as your border is inside container element. which is 1170 px wide … so your border will be only 1170px wide … still if you want to make that border full page …. simply put this <hr class=”featurette-divider __before_main_container”> code snippet outside your main container.
for example your code is like shown below:
<div id=”main-wrapper” class=”container”>
…. all you main content ….
<hr class=”featurette-divider __before_main_container”>
</div>
thus it takes only 1170px width as your container is of 1170px wide.
simply put that hr code outside that code snippet…. and so your code will look like shown below:
<div id=”main-wrapper” class=”container”>
…. all your main content ….
</div>
<hr class=”featurette-divider __before_main_container”>
in this way your border now will be full page width wide. hope you got the point now.
