If I don’t know the hex color value, is there a color picker?
Yes, the color picker is next to the textbox for entering the color. When you click on the square, the color picker tool will appear below the textbox. This color picker works the same as the one in photoshop.
I would like to know how to limit the amount of excerpt data I am displaying: like number of words or number of characters, etc. Sometimes is too much of it and I do not want to fill up the page with big paragraphs of information. Is this possible?
Yes, you can limit the amount of excerpt words by adding these lines in your functions.php file located in your theme directory:
add_filter( 'excerpt_length', 'custom_excerpt_length', 999 );
In the example above, I limited the excerpt to 25 words but you can put any number that you want.
