paragraph line spacing and font size

It’s not possible to help with CSS without seeing your site. You must also make any changes in a Child Theme or using a Custom CSS plugin. Don’t modify theme files – the changes will be lost when WP is updated.

Create a child theme first.

Any styles you add to your child themes style.css file will override the parent file.

Use an add on like Firebug for Firefox to see how your edits look before applying them.

It sounds like you want to manipulate the line height property.

Hi,

Thanks for the information above, that is useful.

I’m trying to change the paragraph font size for my site but can’t figure it out. Any help would be great…

Also, I’m trying to change the font size of the slider heading on the home page but there is no css for this in the editor (I hope that makes sense?!). How would I go about changing this heading?

My site is here https://www.curiousfair.co.uk/

Thanks!

Guy
