Do you know that scripts block parallel download? Which means that if you place scripts tag on top of your CSS tag, the browser will only download and process your CSS file, once the scripts has completely processed. The World Wide Web Consortium(W3C) suggest web developer to place the script tag at the bottom of the page, to avoid the scripts block parallel download.
You should place CSS tag on the top of the page instead of bottom, because placing CSS in HEAD section allows browser to render the page progressively and it also giving visual feedbacks to your visitors, to let them know what is the element is under rendering.
You shouldn’t scale the images in HTML, because the end user browser need time to re-calculate the width and height of the images before the images being render. In addition, you should always specify your image’s original width and height in attribute allows browser to render the image quickly without calculating its width or height.
The use of large number images / image with large file size on your website can create a bad experience for your end user, especially those who have slow internet connection. The end users are required more bandwidth and time to download all the images on your page. There are 2 ways to avoid this problem, you should either optimize the images or use less number of images.
