Font size and color change

You need to add some CSS code. If you’re using a child theme then you add the CSS to that. If not, you could create a child theme then add CSS. Or you could use a plugin such as https://en-gb.www.ads-software.com/plugins/simple-custom-css/ to add CSS.

So you could easily change the font size, by adding something like this to over-ride the current CSS:

body {
font-family: “Whatever font”, sans-serif;
font-size: 16px;
}

If you’re getting into this sort of customisation, you’ll need to learn some basic CSS. How do you know what CSS is in use in your theme? Learn to use the Inspect Element feature in your browser.

Thanks for the info Jason. I am already using that plugin and have inserted few codes
and they are working. Regarding this code to change the font and it’s size, I want to affect only this page but not the rest. Will the code still be same ?

Use the Inspect Element tool in your browser, or view the page’s source code to look the body tag. Then apply the CSS to the relevant page id:

body.page-id-575 {
whatever
}
