CSS Visual Rules

#1

I am stuck at this problem. Need help. Tried every possible way of solving this question.

body {
  /* Old browsers */
  background: #141E30;
  /* Chrome 10-25, Safari 5.1-6 */
  background: -webkit-linear-gradient(-45deg, #35577D, #141E30);
  /* W3C, IE 10+/ Edge, Firefox 16+, Chrome 26+, Opera 12+, Safari 7+ */
  background: linear-gradient(-45deg, #35577D, #141E30);
  margin: 0;
  padding: 0;
}

h1 {
  color: #FFF;
  font-size: 2em;
  padding-top: 100px;
  width: 100%;
  font-family: Georgia;
}

h2 {
  border-bottom: 1px solid rgba(255, 255, 255, 0.5);
  color: rgba(255, 255, 255, 0.5);
  font-weight: 100;
  font-size: 22px;
  line-height: 24px;
  padding-bottom: 30px;
  text-align: left;
  width: 70%;
  font-family: Georgia;
}

p {
  font-weight: bold;
  color: AliceBlue;
  line-height: 1.3em;
  text-align: left;
  width: 100%;
  font-family: Helvetica;
  font-size: 18px;
}

.byline {
  font-family: Helvetica;
  color: rgba(255, 255, 255, 0.5);
  float: left;
  font-size: 14px;
  padding-left: 10px;
  text-transform: uppercase;
}

.caption {
  display: block;
  font-family: 'Playfair Display', serif;
  font-size: 14px;
  font-style: italic;
  line-height: 14px;
  margin-left: 20px;
  padding: 10px;
  position: relative;
  top: 80%;
  width: 60%;
}

.content {
  padding: 40px;
}

.image {
  background-image: url("https://s3.amazonaws.com/codecademy-content/courses/web-101/unit-4/htmlcss1-img_soccer.jpeg");
  background-size: cover;
  background-position: center;
  height: 300px;
}

.writer-img {
  -webkit-box-shadow: 5px 0px 5px 0px rgba(0, 0, 50, 0.97);
  -moz-box-shadow: 5px 0px 5px 0px rgba(0, 0, 50, 0.97);
  box-shadow: 5px 0px 5px 0px rgba(0, 0, 50, 0.97);
  float: left;
  width: 50px;
}

set the font weight of paragraph elements to bold.

Here is how you do it:

p {
 font-weight: bold;
}

Or, in the HTML file connected with this CSS file (if there is an HTML file) where you have written the

tag, write this: 
<p><strong><!--Text You Want To Be Bold Goes Here--></strong></p>
