Customization questions

Sparkling
2

Update:

I figured out the solution for some of them. Not sure they are the right way to do them, though:

#2. Adding class “navbar-fixed-top” to <nav> will do job.
#3. Removing below line from single-content.php:
<?php the_post_thumbnail( ‘sparkling-featured’, array( ‘class’ => ‘single-featured’ )); ?>
#4. replace the_content(); with the_excerpt();
#5. Can be found HERE.
#7. can be edited in functions.php

Also, since I use 336x280 ads, it doesn’t fit in mobile-view. I made these changes to fit it. Please let me know if this is not a good way:

.main-content-inner {
 padding: 5px 5px;
}
.post-inner-content {
  padding: 3% 3%;
}
,site-content {
 padding: 5px 5px;
}
.well {
  padding: 3% 3%;
}
.widget-area {
 padding: 5px 5px;
}

I still need some help with my #1 and #6 questions in first post above.
