What steps can I take to ensure my website project is completely responsive?

Define the Breakpoints: First define the screen sizes that will trigger certain changes in the design of the website. A breakpoint is a point in the width of the display where the design changes.

Use Fluid Layouts: Use relative CSS units such as % or em instead of fixed-size units like pixels (px). This makes sure that the layout adapts to the screen size.

Use Flexible Images: Make sure images do not overflow or stretch beyond their container. Use the max-width: 100% property for images.

Be Mindful of Typography: Make sure that the text on your website is legible on any device. Increase font-size at smaller breakpoints to make sure that the text is not too small.

Use Responsive Navigation: Navigation is key to keeping your website usable on mobile devices. Use a mobile-first approach to design navigation so that it adapts gracefully on smaller screens.

Test on Multiple Devices: Test the website using multiple devices at different screen resolutions to ensure that there are no usability issues on any of them.

Use Media Queries: Use media queries to make targeted changes to the layout at certain breakpoints. This allows for a more streamlined responsive design.
