I am trying to add CSS to the top of HTML generated by DataFrame.to_html() by df.style.set_properties(color="green")
The df.to_html("filename.html") generates the following output
<table border="1" class="dataframe">
......
The question is how can I print the CSS info at the top of the output file?
<a color="green"/a> <=====
<table border="1" class="dataframe">
