Weebly is a website builder that allows users to create their own websites without needing to know how to code. While it does offer a wide range of design options, there may be times when you want to add custom CSS (Cascading Style Sheets) to your site to further customize its appearance. Here are some handy CSS hacks that you can use with Weebly:

  1. Change the font of your text: You can change the font of your text by adding the following code to your site's CSS: "font-family: 'your font name';"
  2. Change the color of your text: You can change the color of your text by adding the following code to your site's CSS: "color: #hexcode;"
  3. Change the background color of your site: You can change the background color of your site by adding the following code to your site's CSS: "background-color: #hexcode;"
  4. Add a background image to your site: You can add a background image to your site by adding the following code to your site's CSS: "background-image: url('imageurl');"
  5. Change the size of an element: You can change the size of an element, such as a header or image, by adding the following code to your site's CSS: "width: pixels; height: pixels;"
  6. Center an element: You can center an element, such as a header or image, by adding the following code to your site's CSS: "text-align: center;"
  7. Remove the Weebly footer: You can remove the Weebly footer by adding the following code to your site's CSS: "#footer-wrap {display: none;}"
  8. Add a hover effect: You can add a hover effect, such as changing the color of a button when someone hovers over it, by adding the following code to your site's CSS: "selector:hover {property: value;}"

It's important to note that to add custom CSS to your Weebly site, you will need to access the site's HTML/CSS editor and add the code to the appropriate area.

It's also recommended to back up your website before making any changes to the site's code, in case something goes wrong.

It's also important to test your changes on different devices and browsers to ensure compatibility.

It's also a good idea to have a general understanding of CSS and its syntax before making any major changes, as it can make debugging and troubleshooting easier.
