I dont think so.
Ah, you dont need visibility: hidden; on .slide-excerpt-border.
That hides text inside.
Sorry, I just checked syntax error on that.

Plus, you just need to set background none on .slide-excerpt

It seems you have set display: none on html > body .slide-excerpt-border.
That would hide everything inside.

That is defined in the plugin’s css.

.slide-excerpt {background-color: #fff;
filter: alpha(opacity=80);
display: block;
margin: 10px;
opacity: 0.8;
padding: 0;
position: absolute;
z-index: 8;}

First, pls check the plugin has a setting page or not.
If it does not, you can overwrite them in style.css of your child theme.
In order to overwrite them, you need to add more specific css rule like:

#genesis-responsive-slider .slide-excerpt {
background-color: transparent;/* remove background color */
filter: alpha(opacity=100);
opacity: 1;
color: black;/* set font color */
}

I think you can add ‘post_parent’ parameter to WP_Query argument.

There are couple of problems I can find.
One is that you load some js files twice in head tag and end of file.

Second, it is necessary to put the following js before loading scrolling-nav.js and after jQuery.
Or you just change ‘bind’ to ‘on’.

$('a.page-scroll').bind('click', function(event) {
to
$('a.page-scroll').on('click', function(event) {

Or it is better add class ‘page-scroll’ on ‘.main-nav li a’, if you can.

I think you can follow “Moving a Root install to its own directory” section of this page.
http://codex.wordpress.org/Giving_WordPress_Its_Own_Directory

You can skip 1,3, and 6, since you have already moved WP core to subdirectory.

It is not recommended to use plugins which is not maintained for long time.
For example, WP changed backend program of visual editor since ver.4.3, and that plugin last updated before then.
Even if it works now, it is doubtful in the future since WP will continue to be upgraded.

I understand it looks complexed, however, using child theme is to avoid total mess.
When something go wrong, you can just quit using that theme and switch back to parent theme or other theme.

If you want to change contents for specific category, say Doctor Games category ( its slug is doctor-games ), duplicate category.php and rename it category-doctor-games.php.
category-{slug}.php is the format. This template file is only used for Doctor Games category page.
You can add as many template file as you need for specific category, and edit content part for each category.

There are some ways to edit contents for category pages via admin pages, but at least you need to prepare child theme and to edit template file first.

some ways like:
– private post with custom fields
– create widget area

That would be bit complexed, I guess.

It is ok to leave inline script as below:

<!-- Script for scrollNav.js -->
<script>
	jQuery(document).ready(function(){
		jQuery('.main-nav li a').addClass('page-scroll');
	});
</script>

scrolling-nav.js needs the above wrapping code.
Or you can just replace $ with jQuery in scrolling-nav.js, too.
