Make images and youtube videos responsive in blogger post
In blogger there are many responsive templates which are free and paid available for download. These templates are very helpful for making the your blog responsive.
Still in some templates, the pictures inserted in the posts are not responsive due to the fixed size options provided by blogger post editor.
In this case you can follow these simple steps to make the picture responsive. This method can also be used if you do not have a responsive template, but want the picture to be of certain percentage of the page body. For example you may want the image to fill the page body by width or you may want the image width to be half the size of the page width.
