If you are using the built-in oEmbed feature of WordPress whereby pasting the URL of a YouTube video inserts the video in your post content, adding the following CSS will make the videos take up the full available width of your content with the videos proportionately sized i.e., behave responsively:

/* Make YouTube videos inserted via WordPress oEmbed full-width */

.embed-youtube {
    overflow: hidden;
    position: relative;
    max-width: 100%;
    height: auto;
    padding-bottom: 56.25%;

.embed-youtube iframe,
.embed-youtube object,
.embed-youtube embed {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
