Usually, when I make a views block list, and I want it horizontal, I would just add CSS styles to the block itself.
#block-views-something li
{
display: inline;
list-style-type: none;
padding-right: 20px;
}
Having to do this for each block is a pain. I know Views 3 lets me add a class to the view to style the list, but I have never been able to do it. I have tried HTML List, and adding classes to Page: Style options Row class, and Wrapper class or even List class. I have tried it with a dot like .mystyle and without the dot 'mystyle'.
In fact, I just get myself into a right old mess. Could anyone advise me the simplest route to take to add the class to whatever box I should add it to?
