Remove multi-color bar/reduce distance

[Am_M]

If you still need to remove the rainbow bar here’s the code:

You can do something like this:

```
hide_decoration_bar_style = '''
    <style>
        header {visibility: hidden;}
    </style>
'''
st.markdown(hide_decoration_bar_style, unsafe_allow_html=True)
```
