hello, i have little bit knowledge about html and have no idea about css can you please describe me what is css?? Also ,please mention some advantages of css thanks.
Without css your page would be all times roman and incredibly ugly. The advantages - you get a page that looks, hopefully, halfway presentable. Is this an assignment or do you really not understand?
In short, CSS makes styling and maintaining websites significantly easier and time-saving. Let's take coloring text for example. Without CSS, we have to set/change font color for elements one by one; with CSS, we can just write a line of CSS code and change all elements' text color at once. Besides, CSS can also achieve many kinds of layouts such as floating, positioning, and flex box, which old means are impossible or very hard to achieve.
