Schreiben Sie den Titel um in: Wie platziere ich mein Logo in der oberen linken Ecke der Kopfzeile?

Question

Ich entwerfe eine Kopfzeile für mein College-Projekt, bei der sich das Logo in der oberen linken Ecke befinden soll. Ich habe versucht, die Float-Eigenschaft in CSS zu verwenden, aber es ist nichts passiert. Wie verschiebe ich mein Logo in die obere linke Ecke der Titelleiste? Ich habe es viele Male versucht, aber der Code wird nicht ausgeführt.

Answer 1

只需将您的.logo元素和p标签放在一个div中。它会自动排序。

您还忘记了在按钮周围关闭a标签。

在布局中不要使用浮动或绝对定位，除非您知道自己在做什么...

Answer 2

您的header具有padding: 30px 10%，这意味着header的左右两侧会有10%的填充，然后在.logo中，您将起始位置设置为距离左侧20px。

一种“修复”它的方法是通过left: calc(-10% + 20px);来使.logo的left处于负位置。

@import url('https://fonts.googleapis.com/css2?family=Montserrat+Alternates:ital,wght@0,500;1,400&display=swap') * {
  box-sizing: border-box;
  margin: 0;
  padding: 0;
  background-color: #F5F5F5;
}

li,
a,
button {
  font-family: "Montserrat", sans-serif;
  font-weight: 500;
  font-size: 16px;
  color: #000000;
  text-decoration: none;
}

header {
  display: flex;
  justify-content: space-between;
  align-items: center;
  padding: 30px 10%;
  background: linear-gradient(rgba(165, 246, 144, 0.3) 0%, rgba(158, 249, 216, 0.63) 100%);
  height: 56px;
}

p {
  position: absolute;
  width: 584px;
  height: 67px;
  left: 232px;
  top: 25px;
  text-shadow: 0px 4px 4px rgba(0, 0, 0, 0.25);
  background: url(pharmapp.png);
  align-items: center;

  font-style: italic;

}

.logo {
  position: relative;
  float: left;
  margin-block-start: 10px;
  background: url(pharmapp.png);
  height: 122px;
  /*you can play with the numbers here*/
  left: calc(-10% + 20px);
  top: 0px;
  bottom: 40px;
}
