Hi huanling,
- You can open the file: [root]/templates/ja_lens/css/template.css
At approx line 714, you will see this CSS code:
#logo h1 a {
color: #fff;
padding-left: 0px;
width: 60px;
height: 60px;
line-height: 60px;
background: url(../images/logo.png) no-repeat center center;
display: block;
font-size: 0px;
text-indent: -9999em;
}
it's using [root]/templates/ja_lens/images/logo.png as logo of template, you can change to your own one there.
2.1: you can go to Backend > Menus > open the 'Home' menu item of your site and change the page title there: http://prntscr.com/ktu6kc
2.2: Go to this file: [root]/templates/ja_lens/index.php
Find these lines of code:
<h4><span>Categories</span></h4>
change to:
<h4><span><?php echo JText::_(TPL_CATEGORIES); ?></span></h4>
and:
<h4><span>Timeline</span></h4>
change to:
<h4><span><?php echo JText::_(TPL_TIMELINE); ?></span></h4>
Then access Backend > Extensions > Language(s) > Overrides and add this translation:
TPL_CATEGORIES = "your_own_text_here"
TPL_TIMELINE = "your_own_text_here"
2.3: In the same section for language overrides, add the translation for below constants:
TPL_FINISHED_MESSAGE = "That\'s all we have for now 🙁"
TPL_LOADING_MESSAGE = "<em>Roger that Sir! I\'m on my way...</em>"
