Please see the questions I have! thanks :)

Hi Jonathan.
The site exercisingcap.com that you have sent us, is not using any of our theme.
Can you please send us your site that using our theme for further checking?

1.I tried going in appearance>editor>styles.css and its blank without anything to edit..? How to get this back?
Our files are located in CSS folder in the path: your site > wp-content > themes > assets > css.
You cannot access to these file via Editor  (appearance > editor).
We use the file style.css to call actions in theme not to edit and style in this file

2. Some of my posts has a ‘smiley’ and when I decrease window size the icon stretches entirely which isn’t something I ever saw before in other themes…how to fix this?
Please add the following code to Header code in  Dashboard > Appearance > Customize > Custom code > Header Code

<style>
@media (max-width: 719px) {
 .item-content img, .post-content img {
 width: auto;
 }
}
</style>

 
3. Is there a way to widen the main sidebar widget?
To widen the main sidebar please add following code to header code in  Dashboard > Appearance > Customize > Custom code > Header Code

<style>
@media (min-width: 986px) {
 #main {
 padding-left: 200px
 }
 #sidebar {
 width: 200px;
 }
}
</style>

 
4. How to center the header titles in all widgets?
To center the header titles in all widgets please add following code to header code in  Dashboard > Appearance > Customize > Custom code > Header Code

<style>

5. is there a way to center the template instead of the extreme left side for the blog posts?

<?php get_sidebar(); ?>

<style>
@media(min-width: 1011px){
 .page-template-layout-blog-php #header-inner,
 .page-template-layout-blog-php #container {
 max-width: 980px;
 margin: 0 auto;
 }
 .page-template-layout-blog-php #main {
 padding-left: 0;
 }
