Edit the page in Advanced Mode (from Sharepoint Designer). If the button "Advance Mode" is grayed out, enable "Enable Detaching Pages from the Site Definition". You can find this setting on the site in the section "SharePoint Designer Settings" (http://site-name/_layouts/15/SharePointDesignerSettings.aspx) If this option is also disabled at site settings level, go to central admin > web application > General Settings > SharePoint Designer Settings and select the checkbox to enabled detaching.
