in my yii2 template I find at the bottom of <div class=“container”> tags tags like <font color="#ff0000">. What are they for? I didn’t declare them so they must be generated by Yii. And why is the <footer> tag declared within such a <font> tag and not right below a <div container> at the same level as <header>? And how can I move the <footer> (or other tags I declared) out of that tag?
