CSS / Эцсийн төсөл

Эцсийн төсөл

CSS курсийн эцсийн төслийг хийх цаг боллоо. HTML курст хийсэн portfolio хуудасны бүтцийг авч, CSS-ийн сурсан бүх зүйлээрээ гоёмсог болгоно.

Юу хийх вэ?

HTML курст бүтцийг нь тавьсан portfolio хуудсыг дараах CSS техникүүдээр шинэчлэнэ:

  • Custom property (design system)
  • Flexbox ба Grid layout
  • Responsive дизайн (mobile-first)
  • Transition ба animation
  • Pseudo-class, pseudo-element
  • Box shadow, gradient, border-radius
