How to fix errors from www.validator.w3.org

Line 184, Column 35: No p element in scope but a p end tag seen.

Find the file of this HTML and delete the <p> tag or add another one. It depends on what markup you want to use.

Line 183, Column 388: The scrolling attribute on the iframe element is obsolete. Use CSS instead.

The scrolling attribute is no longer in use. Try to do the same effect with css. Try this one, if it does not work google something ??

overflow-x: hidden;
overflow-y: auto;

Line 183, Column 388: The frameborder attribute on the iframe element is obsolete. Use CSS instead.

Here is the same, the frameborder attribute is no longer in use. Try to solve this with css with border-width.

Line 181, Column 10: No p element in scope but a p end tag seen.

Line 176, Column 10: No p element in scope but a p end tag seen.

Here you have not closed <p> tag.
