    1. Hi Kyre, sorry to hear that you’re running into trouble altering the font size. It’s likely that the font size for certain parts of the site is directly coded into the theme itself. I’d suggest posting on the Alante theme’s support page and asking for assistance. With specialty themes and plugins, it’s always a good idea to check with the developers, as the “normal” way of doing things for WordPress can end up being different.

  1. Thanks for this. Can you tell me how to change the actual Page Paragraph font size – so not a header but the ordinary font – I can’t seem to find an option for this in the CSS editor…I’m using Alante Blue theme. Thanks. 

    1. To change the font size for the paragraphs on the site you would want to edit the CSS section for the paragraph tags “

      ” or find the div your theme is using for the areas you want to change and add the font-size attribute to the div.

  2. Thank you for your article. When I get to the stage of or editing pages I get the intro code with author, etc, but none of the code to engage with. I could cut and paste from my GoDaddy file manager, but you say that it should show in the field by oopening. I opened my index page then Appearance, Edit, and I get  noe code except into. I would send a screen shot but I do’nt see that option here.

    Thanks for any help you may be able to provide. RW Huntley.

    1. Thanks for your question. You will want to make sure to click Appearance > Editor. Then, make sure that you edit the stylesheet. As mentioned above, it is wise to complete this in a child theme.
