💡[FEATURE]: Changes in the header

**Is your feature request related to a problem? Please describe.**
I want to fix the header component to be fixed like when i scroll down even though i can able to see the header and also i want to fix the error like when i am in the home or about or any other page then it must be bold so can we know which page we are in now for better user experience.

**Describe the solution you'd like**
I want to add bold the current header item like if we are in home the home must be bold and also there are some items of headers are in capitals and some are in normal and also fix this by using normal and fix the header if needed.

**Describe alternatives you've considered**
In alternative there is not any particular requirement for fixing the header but the fixing the capitalize the text and bold the text is needed.
As we can see in the above image we are not able to find which page we are in Because all the text in the header are same.
