In this course reflection, Andrea Mark summarizes what she learned in Module 5 about designing documents, slides, and screens. She learned that good design saves time and money while building goodwill, and that fonts, headings, and whitespace create an appealing aesthetic. She practiced these concepts in assignments analyzing a webpage and designing a letter. Andrea recognizes the significance of design, stating it is as important as content, and that without strong design skills her future marketing company would not be taken seriously. Moving forward, she will apply these design principles to make future papers visually interesting for readers.
