Validating data from database php
For this we will use many CSS Styles, so I think the better way is use an external file and link it to the webpage.

One profile page and other ID and password validation.For checking or validating the ID and Password we need to save ID and Password to the database, for this we need two more things as a database and a table.

POST is commonly being used for these kind of webpages, due to its security.Figure 2: Output of the Sign-in Webpage with updated size of fieldset tag As you can see in the Listing 1 and 2 we used such a good Html tags to design a simple log-in form.
