Why are you here? Why are you visiting us?
Is it because you have started writing a web page using a product that promises "no code" web pages and you want to make a simple change to the way the page looks but do not have the faintest idea how to change the code to make the page look the way you wish?
One cannot realistically write a decent web page without having a working knowledge of HTML and CSS code. The promise of designing a web page without code only goes as far as the design limits of the product (Adobe Muse, in this case) permit.
Learning HMTL and CSS isn't that hard. It takes time and practice to learn how the elements and properties behave and interact, but that's fun.
If you do not wish to invest in yourself, then Adobe offers instructions, tutorials, and a user community where you can receive help using their product.
