Khi làm responsive vấn đề đau đầu nhất với lập trình viên Front-End đó là làm sao chọn ra các breakpoint chuẩn để viết CSS tương thích với các kích thước màn hình. Phần lớn chúng ta sẽ chọn các breakpoint theo các kích thước của Bootstrap, nhưng nếu bạn muốn đầy đủ hơn, hãy thử tham khảo bài viết này nhé
Lưu ý: Tất quả queries đều ở dạng min/max-device-width tức được detect theo đúng kích thước màn hình thật của thiết bị, nên nếu bạn test trên PC kiểu thay đổi width browser để responsive sẽ không thấy CSS được áp dụng, nếu muốn hãy bỏ tiền tố device đi để có thể test thay đổi trên PC

II. SASS
Với SASS bạn có thể viết mixin để gọi sử dụng như sau
// init
$breakpoints: (
'laptop-non-retina' : '(min-device-width: 1200px) and (max-device-width: 1600px) and (-webkit-min-device-pixel-ratio: 1)'
);
@mixin breakpoint($breakpoint) {
$raw-query: map-get($breakpoints, $breakpoint);
@if $raw-query {
@media #{$raw-query} {
@content;
}
} @else {
@error 'No value found for `#{$breakpoint}`. ' + 'Please make sure it is defined in `$breakpoints` map.';
}
}
// use
h1 {
font-size: 5rem;
@include breakpoint('laptop-non-retina') {
font-size: 2rem;
}
}

Mình thử chèn code Auto Ads của AdSense vào trong blogspot bên dưới thẻ :
[pre]<b:if cond='data:view.isPost'>
<script async='async' src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
<script>//<![CDATA[
(adsbygoogle = window.adsbygoogle || []).push({
google_ad_client: "ca-pub-XXXXXXXXXXXXXXXX",
enable_page_level_ads: true
});//]]>
</script>
</b:if>[/pre]
Nhưng nó chẳng hiện gì hết! Nhờ bác có thể hướng dẫn làm sao cho nó hiện được ads trong blogger được không ạ!
Bác có thể kiểm tra trên blog của mình:
