How to make my blog homepage display 1 line of tags instead of 2?

Using Ghost
1

I don’t know what happened.
In my ghost website’s homepage, the tags were perfectly displayed in the site head, in only one line
now, it’s in two
for example
before it was

tag#1 tag#2 tag#3 tag#4 tag#5 tag#6

now, it is

tag#1 tag#2 tag#3 tag#4 tag#5
tag#6

How do I make it be like it was before?
