The best and permanent way is to create custom theme (or modify default one) and add general meta-tags, javascript / css files (which you want to appear on each page of portal) through head section of theme's portal_normal.vm file. However, if you want to restrict these tags for specific page(s) you can still do it through Velocity Objects like public / private layout, admin / user difference, current page name / URL, there are numerous options available.

The other possible and quick way is to add js / css dynamically using javascript / jQuery as following:

if you are using pure javascript:

window.onload = function(){
    loadjscssfile("myscript.js", "js");
    loadjscssfile("javascript.php", "js");
    loadjscssfile("mystyle.css", "css");
}

Or you can use jQuery:

jQuery(function(){
    loadjscssfile("myscript.js", "js");
    loadjscssfile("javascript.php", "js");
    loadjscssfile("mystyle.css", "css");
});

general method:

function loadjscssfile(filename, filetype){
    if (filetype=="js"){
        var fileref=document.createElement('script')
        fileref.setAttribute("type","text/javascript")
        fileref.setAttribute("src", filename)
    }
    else if (filetype=="css"){
        var fileref=document.createElement("link")
        fileref.setAttribute("rel", "stylesheet")
        fileref.setAttribute("type", "text/css")
        fileref.setAttribute("href", filename)
    }
    if (typeof fileref!="undefined")
        document.getElementsByTagName("head")[0].appendChild(fileref);
}

Add above code to the javascript section of the root of your pages.
