Changing font size on javaScript : Im currently trying to change the FontSize of the Letters "Se Habla Espanol" 

So Im relative New to Javascript .... And well during the process of the me playing with the website i  got into the following problem.

This is what i currently have...


    <body>
     
    <font color="yellow">
    <script>
    function blinker() {
    $('.blinking').fadeOut(500);
    $('.blinking').fadeIn(500);
    }
    
    setInterval(blinker, 1000);
    
    </script>
    
    <center>
    
    <p class="blinking">se habla Espanol</p>
    
    </center>
    
    
    </font>
    
    </body>



I was thinking of using the following code but it seem that is only responsive to HTML and not javascript

    <font size="+2">This is bigger text.</font>



This is what i had in mind so my work is not really accurate everything is taken from the internet

--This is what i attempted to do but didn't work :

    
    <center>
    <font size="+2">
    <p class="blinking">se habla Espanol</p>
    </font>
    
    </center>
