How Do I Create a Media Query in WordPress?

Creating a media query in WordPress is a fairly simple process. To begin, open up your theme’s functions.

php file and locate the query_vars() function. Within this function, add the following line of code:.

// Sets the query variables for the theme // Add your media queries here. wp_enqueue_media() will take care of the rest.

function query_vars() { // Add your media queries here. wp_enqueue_media(); }.

Next, you’ll need to create two custom functions. The first is called media_query() and will be used to define the conditions under which your media queries will be active.

The second is called media_query_attributes() and will be used to define the attributes that your media queries will be checking for.

To create the media_query() function, open up a new file in your favorite editor and paste the following code into it:

function media_query() { // The query is made up of three parts. // The first is the type of media. // The second is the condition.

// The third is the attribute. // All of these must be placed within a single // quotes. $type = ‘all'; $cond = ‘any'; $attrib = ‘none'; }.

Next, you’ll need to define the conditions that your media queries will be active for. To do this, you’ll need to create two arrays.

The first array will be called media_query_attributes and will contain the attributes that your media queries will be checking for. The second array will be called media_query_extra and will contain any additional variables that you want to use.

To create the media_query_attributes array, open up a new file in your favorite editor and paste the following code into it:

// The attributes that will be checked. // Each attribute must be placed within a separate // quotes. $attribs = array( ‘type’ => ‘all’, ‘cond’ => ‘any’, ‘attrib’ => ‘none’ );

Next, you’ll need to create the media_query_extra array. To do this, open up a new file in your favorite editor and paste the following code into it:

// Any additional variables that you want to use. // Each variable must be placed within a separate // quotes. $extra = array( ‘max-width’ => ‘98%’, ‘max-height’ => ‘98%’, ‘responsive’ => true, ‘margin-top’ => ‘0px’, ‘margin-bottom’ => ‘0px’, ‘padding-top’ => ‘0px’, ‘padding-bottom’ => ‘0px’ );

Now that you have the arrays created, you’ll need to define the media_query() function’s parameters. To do this, you’ll need to add the following line of code to the function:

$type = ‘all';

Next, you’ll need to define the media_query_attributes array’s parameters. To do this, you’ll need to add the following line of code to the function:

$attribs = array( ‘type’ => $type, ‘cond’ => $cond, ‘attrib’ => $attribs );

Finally, you’ll need to define the media_query_extra array’s parameters. To do this, you’ll need to add the following line of code to the function:

$extra = array( ‘max-width’ => $max_width, ‘max-height’ => $max_height, ‘responsive’ => $responsive, ‘margin-top’ => $margin_top, ‘margin-bottom’ => $margin_bottom, ‘padding-top’ => $padding_top, ‘padding-bottom’ => $padding_bottom );

Now that you have all of the code in place, you can save your file and return to your theme’s functions.php file. Within this file, you’ll need to add the following line of code to activate your media queries:

wp_enqueue_media( ‘media_query’, ‘media_query_attributes’ );

Finally, you’ll need to add the following line of code to your theme’s final HTML file to define the media queries:
