Question

I am doing the beginning of a work for the course and in the code the <h1>, <hr>, and the <marquee> do not want to jump columns with the .offset Follows code:

<div class="container">
    <div class="row">
        <div class="col-md-5 col-md-offset-2">
            <h1>Acróstico de Lucas</h1>
        </div>
    </div>              
    <div class="row">
        <div class="col-md-6 col-md-offset-5">
            <hr color="black"></hr>
        </div>
    </div>
    <div class="row">
        <div class="col-md-6 col-md-offset-5">
            <marquee behavior="slide" direction="down" loop="1" scrolldelay="60">
