Help with footer and post options

Oh and by the way my site is https://www.niketyi.com I’m not launching it til tomorrow but I can open it up to allow someone to help me. Thx in advance.

I figured out how to change the text in my footer.

Now I’m trying to figure out how to change my post order. Right now all new posts are showing up on the bottom instead of on top. HELP!

I fixed that issue as well. How come no one is responding?

Now I want to figure out how to:

Change font color
Change to show post excerpts so “click more” has to be selected to read post in its entirety

Thank you in advance

1)Change font color …on which element you are talking, i mean whether whole body content or titles or something else depending on that you need to target css

For example changing post title color

.article h2.post-title a {
     color: #F00;
}

2)As i checked you already created child theme , now you need to copy the content-list.php from parent theme and paste it in child theme

and go to line where it says

<?php the_content(); ?>

change it to

<?php the_excerpt(); ?>

Thank you!
