how to make logo in header??

Answer 1

for example:
<header>
<img src=" https://encrypted-tbn1.gstatic.com/images?q=tbn:ANd9GcSPxHRF7JKRsMHbjfUZ9hX93Ue_O05jh3FGfu1LmXSm98Zq7YEWK-1YDBFRFg" alt="" />
</header>

But you still need to give it width, height, position etc.. So use a CSS to style it

Answer 2

put it in the header tag as an image. either do the styling in the image tag so that it is well positioned or add a class and use CSS for the styling
