Fix the Incase. As above it's not a real word.
The syntax is also in need of attention.
"this website was only designed using html and css"
Should be "this website was designed using only html and css", if that is what you mean.
"I am" is two words, you have "Iam" throughout the site. Iam is not a word.
"there are various discussion categories available in the forum for discussion"
The first "discussion" is a redundant word.
Try
"there are various categories available in the forum for discussion"
Or
"there are various discussion categories available in the forum"
People shopping for website design are immediately put off by spelling, grammatical and syntax errors. It needs to be 100% perfect to convey the sense of intelligent design capability. If I was wanting a website, I would only seek services from someone that displayed that capability.
The readability and layout is a vast improvent however.
Hope that helps.
