Not sure you mentioned Text size tool at the top right conner of the template or the text size of Text logo.
If Text size tool: please edit default font size via Template Manager (Extensions >> Template Manager), click on JA_Teline_II name, you will be directed to JA Teline II configuration
If Text logo, you can edit template.css file as follows:
– In line 796 (to edit Logo Text) : edit the value in red:
<blockquote>h1.logo, h1.logo-text {
margin: 0;
padding: 0;
font-size: 300%;
}</blockquote>
– In line 68 (To edit Slogan):
Replace:
<blockquote>small, .small, .smalldark, .createby, .createdate, .modifydate, .img_caption, p.site-slogan, a.readon, #ja-pathway, #ja-footer {
font-size: 92%;}</blockquote>
With:
<blockquote>small, .small, .smalldark, .createby, .createdate, .modifydate, .img_caption,
a.readon, #ja-pathway, #ja-footer {
font-size: 92%;
}
p.site-slogan {
font-size:100%; // you can edit the size as you want
}</blockquote>
