Some small queries

I have removed the code but it was showing on BlogPage(www.staymeonline.com/blog) and on deals page(www.staymeonline.com/deals)
These are two pages...

That code will target all links within your content, including WP Show Posts.

You can try adding this as well:

.entry-content .wp-show-posts a,
.entry-content .wp-show-posts a:visited,
.entry-content .wp-show-posts a:hover {
    text-decoration: none;
}
