BoldR wrong conent display

i just used Custom CSS plugin…
I make a change with postmetadata div and now it’s look that : https://numer-konta-bankowego.pl/placenie-karta-przez-internet/

I want to add some margins arround the content and remove the margin under the “BLOG” bar on footer menu… How can I do that?
Thanks You

Add the below css for space around content

.post-content {
    padding:15px;
}

For the margin under your gray bar.. change your margin-bottom from 40px to 0 like below

hr {
    border: solid #eee;
    border-width: 3px 0 0;
    clear: both;
    margin: 20px 0 0; /* margin:20px 0 40px;  Orginal */
    height: 0;
}

hello
padding is working, but the second code does nothing ;/ it’s still looks the same

I want to all content looks like there https://numer-konta-bankowego.pl/numer-konta-bankowego-ekonto/ without this margin in the top of content between content and navibar
