Bolding Headers

@azizwaing: You can add the following CSS in “Appearance => Theme Options => Custom CSS” box to bold the tile in the slider
#main-slider .entry-title { font-weight: bold; }

Looks like you have customize the core theme file style.css . You shouldn’t edit any core theme files. It will be reverted back when you perform update to theme. I see that you have changed style.css reset font to font-size: 13px; this should be font-size: 100%; as this is very important for responsive design.

@azizwaing: You can reduce the font size of each elements. You can simply add the following CSS in “Appearance => Theme Options => Custom CSS” box.

@media screen and (min-width: 1060px) {
body,
button,
input,
select,
textarea {
	font-size: 13px;
}
.entry-header .entry-title {
    font-size: 13px;
}
.entry-meta,
#site-generator {
	font-size: 11px;
	font-size: 1.1rem;	
}
#featured-post .entry-title,
.page-links {
	font-size: 13px;
}
.widget-title {
	font-size: 13px;	
}
}

@azizwaing: You can add the following CSS in “Appearance => Theme Options => Custom CSS” box for point 1 and 2

.page .entry-header .entry-title { font-weight: bold; }
#featured-post img.wp-post-image { box-shadow: none; }

But for point 3, I am not clear about it.

@azizwaing: Not sure which area you mean. Maybe add your screenshot image url showing the area.

@azizwaing: You can add the border by adding in the following CSS in “Appearance = Theme Options => Custom CSS” box.
.site { border: 1px solid #00A2E8; }

About the featured post slider, you can set to all pages through “Appearance => Theme Options => Featured Post Slider => Slider Options = > Enable Slider” to “Entire Site”

You can add your posts as featured image. See the instructions at catchthemes.com/theme-instructions/catch-everest/

@azizwaing:

1) How can I change the font size of the content inside the menu drop down bar?
— You can add the following CSS in “Appearance => Theme Options => Custom CSS” box.
#header-menu ul.menu ul a { font-size: 10px; }

2) Is there a way to put text/images to the right side of the header?
— For this you need to upgrade to Catch Everest Pro theme, where you will get Header Right Sidebar and then add anything you want.

3) When you enable the slider for the entire site, is there a way to designate certain slides for certain pages? I don’t want accounting slides to appear for the travel & tours section.
— Sorry there is no option for this. You are only allowed to use same slider throughout the site.

4) Is there a way to remove the “Powered by: WordPress” text in the footer?
— For this you need to upgrade to Catch Everest Pro theme, where you will get Footer Editor in Theme Options panel where you can delete or edit the footer text.

5) How can you link “Click Here” buttons to certain pages?
— I don’t get it what you mean. You can add html links.

6) Is there a way to link image slider pictures to certain pages?
— For this you need to upgrade to Catch Everest Pro theme, where there is Featured Image Slider which can link to any page, post, category, or custom url.
