It has a significant impact on your visitors deciding if they want to stay in your website and check it out or simply press the back button and leave it. how you design a navbar for your website depends completely on your taste and your target audience. It all comes down to your imagination and creativity to make the most intuitive and accessible navbar which is does not bore the visitors. The most common navbar is a horizontal one. it can have many designs and different styles.
