Increase default character size

Hi, thank you for yours answers. I need another suggestion: I can increase default character size without using aAA link in footer?

Thank you!

That component is increasing fonts in all text fields on page proportionally
You can enter
template_css.css,
layout.css
And manually increase font size everywhere you see font-size property.

Or you can (I do not recommend this) simulate click on page load. To do that add this to index.php of template or in some custom module:
<script type="text/javascript">
jQuery(document).ready(function(){
jQuery(".increaseFont").click();
});
</script>

I've increased all values of font-size:10px in template_css.css from 10 to 11, and only one of font-size:11px from 11 to 12 in layout.css

Is necessary that I modify fontResizefile.js in jf folder?

No, it takes current values and adds them value, there are no fixed sizes defined there.

If I add

font-size: 12px;

to "body" in layout.css it increases the default size. Are there any contingent problems on doing that as a simpler way?

you can do , that. Where font should have other size that is defined for that , so you will not have problems.
