You can add support to perform validation in client script.
That way, the display area for the field is static and won't change the page flow if an error message is displayed.
Sometimes you have to validate information that doesn't come directly from an HTML form.
You might also have certain restrictions on the values.
Even if users correctly enter an integer, for example, you might need to make sure that the value falls within a certain range.
A disadvantage of this approach is that users don't know that they've made an error until after they submit the page.
If a form is long or complex, reporting errors only after the page is submitted can be inconvenient to the user.
In many cases, the values you need are some other data types, like integers or dates.
Therefore, you also have to make sure that the values that users enter can be correctly converted to the appropriate data types.
