TY, that worked. Did I need the double quotes since I was trying to remove single quotes?

Your original post contains 5 single quotes. When I removed the extra quote I got an unmatched error. Though I can't remember why, it is necessary to use double quotes in this circumstance.

We can avoid escaping the single quote by generating the character.
This technique is useful for special shell characters and unprintable characters.
Code:
quote_char=$(echo "\0047\c")
echo "style=''" | sed -e "s/${quote_char}${quote_char}/NEWSTRING/g"

style=NEWSTRING

You don't need the \ inside "". For sed they are normal characters, quoting is only used to protect from the shell:
Code:
sed "s/style=''//"

outside the double quotes we need to escape them with a \ :
Code:
sed s/style=\'\'//

we can't escape (\) single quotes inside single quotes, so we have to end the quotes before we can specify escaped single quotes...
Code:
sed 's/style='\'\''//'
