Change location of error message on VF page

How can I change the location of error message.? I have a button which when clicked if required fields are not filled then I want to display error message above the button.

Now it's displaying on top of the page. I want to change the location of the error message. Changed in CSS to display bottom. Still no luck.Anything that I am missing.???

Hi Linda,

Greetings to you!

You can display an error message to a particular field in VF page. You need to use addError on the field in question, which also implies that you must directly bind the field to an apex:inputField. If the field is not directly bound to a visible input, it will appear at the top of the page.

Visualforce: 
<apex:page controller="ErrorMessageC">
    <apex:form>
        <apex:pageBlock>
            <apex:pageBlockSection columns="1">
                <apex:inputField value="{!record.Name}" />
            </apex:pageBlockSection>
            <apex:pageBlockButtons>
                <apex:commandButton action="{!save}" value="Save" />
            </apex:pageBlockButtons>
        </apex:pageBlock>
    </apex:form>
</apex:page>

Controller: 
public class ErrorMessageC {
    
    public Account record { get; set; }
    
    public ErrorMessageC() {
        record = new Account();
    }

    public void save() {
        if(record.Name == null) {
            record.Name.addError('You must enter a value!');
        }
    }
}
