Click an image below and enter your desired text in the input boxes. Choose a color and icon if applicable, and click the Create button to generate html code. Copy that html code and go to Moodle. Click the "Edit mode" toggle at the top right and click "Add an activity or resource". Choose "Label" and click the </> button (generally in the upper right) to enter html mode. Replace the text there with the code you copied, and then click the "Save and return to course button" at the bottom.
